Chapter.1
Statement of the problem
The prices gas cylinders have increased and
we are not able to afford the increasing
price of the gas cylinder. So, I have chosen
to buy a microwave that consumes less
electricity. Therefore, I want to buy a good
company microwave with less cost.

3. Objective
To gain knowledge about the following
aspects:
To learn how the microwave was invented
and what was is its origin.
To learn the mechanism and the working of
a microwave.
To know how many people use microwave
instead of a gas stove.

4. To learn about diseases are caused by
over-usage of microwave. To learn
about the consumption of electricity of
a microwave.
To learn how much money is saved by
using microwave instead of using a gas
stove.
To learn how many people use the
different companies of microwave
among the four that I am looking at.

5. Introduction
This planet Earth was started with a big bang.
Everything used by the people was natural. In the
beginning the man didn’t know what to use or what to
do when he faced problems. People then did the works
physically. They never stressed their minds to work. For
example, if they were hungry or wanted to travel a
huge mile to reach their designation; they simply
walked where they had to move or go. If they were
hungry they simply went in search of food and
sometimes followed the process of agriculture to feed
themselves.

6. Aren’t these methods very lengthy and time
consuming? Yes, of course they are. They are very
straining and tired giving processes. After a billion and
trillions of years after the Earth was formed, there is a
lot of changes and lot of differences. Man has become
very busy and spends most of his time in searching
new methods for making the things and works easier
and quick. He wants the works to be completed
within fractions of seconds without body stress.
Nowadays, man is straining his mind instead of body.
Most of the scientists and biologists spend their time
in searching new methods or inventing things that
makes the work faster and easier. This is why the
people are being lazier and lazier day by day.

7. Nowadays, unexplainable diseases
have come into play. Even though the
diseases are very severe, the man is
finds a vaccine to cure it in seconds.
But these vaccines may cause side
effects. Again to cure these side effects
man finds another vaccine.

8. If you have noticed it life span of the people
has become down due to these modern
inventions. This age has become ‘A Modern
age with Modern Diseases!!!’
One such invention is the ‘Microwave’.
Even it causes diseases and side effects. This
machine is usually referred as ‘Slow
Poisoning’ which means the poison that
reacts very slowly but efficiently.

9. Microwave has many uses. These uses are the
indication for the ‘DEATH and DISEASES’.
Microwave is used in many places. There are
even some place where the microwave is acting
as the heart of the work. Without this machine
the work cannot be completed. Its one main
advantage is that, it cooks food evenly and
efficiently without making it messy and burnt.
This is the feature for which many people are
using it for.

10. The idea of the microwave came when the
scientist was working on radar of a device. It
produced a lot of heat that melted the caramel
chocolate kept aside. So, this idea was revised
and used in microwave to cook food. This story
was about the past of mechanism of the
microwave. But using this idea, mechanics have
put latest and revised features in this machine
and further many companies for profit started to
produce this machine.

11. for this machine. I have decided to buy a
microwave for baking even though I know
that it is going to harm my health. But I
even decided to use it in a limited quantity.
As it is obvious that ‘TOO MUCH IS TOO
BAD’.
Isn’t it really very magical that a
device can produce heat? Isn’t it very
difficult to believe it? But it is the time to
move on with modernity and believe
unbelievable facts.

12. So, let us learn about this wonderful
gadget and how works and even
estimate that which is the best
company of microwave in today’s RLE
report on the topic ‘MICROWAVE
OVEN’.

13. Methodology
I began my project by starting with the Secondary
Data Approval.. After struggling for many a times I got
my Secondary Data approved. I was not much happy
because I had many tasks to complete after taking this
approval. After a great gap of time sir explained us
how to prepare the questionnaire for the relevant
topic. After the explanation we began to prepare the
questionnaire and again in the process to take
approval for the questionnaire. After a great struggle
for many times a I got my questionnaire approved.
Next step of difficulty was the SURVEY.

14. In the scorching sun I moved from house to
house in search of houses that used the
microwave. Many didn’t use microwave and
at that moment I had move to the next
house. But I found 25 houses who were
kind and helped me a lot in completing my
survey. I surveyed many colonies in Ballari
like: Ghandi Nagar, Basaveshwara Nagar,
Nehru Colony, Parvathi Nagar,Siddartha
Colony and etc. After a great struggle I am
doing my report on the scheduled date.

15. coming to school and taking the approval.
It was quite difficult for me to take approval
for the secondary data. I had to be through
with my topic from the tip to tip.
In the survey I faced many problems people
were not willing to answer to my queries.
They said come in the morning. If I went in
the morning they asked to come in the
afternoon.
If I went in the afternoon, they asked me to
come in evenings. Many people didn’t use

16. As if I was a salesgirl.
I many people not answering to my
queries but I found some people who
answered to me so kindly and helped to
complete my survey successfully with
good intention.
It was good to get comets and move on
After a great struggle I and here to do
the report.

17. A microwave oven is shortened and
written as microwave. It is a kitchen
appliance that heats the food with the
help of electromagnetic radiation.
Electromagnetic energy is a term used
to describe all the different kinds of
energies released into space by stars
such as the Sun.

18. They are also useful for quick heating of or
slowly prepared cooking items, such as
hot butter, fats, and chocolate. Unlike
conventional ovens, microwave ovens
usually do not directly brown or caramelize
food, since they rarely attain the necessary
temperatures to produce Maillard
reactions. Maillard reactions mean a
chemical reaction between amino
acids and reducing sugars that gives
browned foods their desirable flavor.

19. Cavity magnetron
It was with the invention of the cavity
magnetron that the production
of electromagnetic wavesof a small
enough wavelength (microwaves)
became possible. The magnetron was
originally a crucial component in the
development of short
wavelength radar during World War II.

20. Uses
Microwave ovens are generally used for time
efficiency, in both commercial applications, such as
restaurants, in the office and at 18
home, rather than for cooking quality, although some
modern recipes using microwave ovens are better
than the recipes using traditional ovens and stoves.
Professional chefs generally find microwave ovens to
be of limited usefulness because browning,
caramelisation, and other flavor-enhancing reactions
cannot occur due to the temperature range.

21. On the other hand, people who want to cook fast, use
microwave ovens to prepare food or to reheat
frozen/stored food in only a few minutes. Microwave
ovens can also be used to defrost items that will later
be cooked by traditional methods, reducing the time it
takes to defrost foods naturally. Microwave ovens are
also useful for the ease with which they can perform
some traditionally cumbersome kitchen tasks, such as
softening butter or melting chocolate, warming milk to
set curds, heating garlic pods so they can be peeled
easily etc.

22. Effects on health
Exposure to microwave
Radiation can produce cataracts by this mechanism,
because the microwave heating denatures proteins in
the crystalline lens of the eye (in the same way that heat
turns egg whites white and opaque). The lens and cornea of
the eye are especially vulnerable because they contain
no vessels that can carry away heat. Exposure to heavy
doses of microwave radiation (as from an oven that has been
tampered with to allow operation even with the door open)
can produce heat damage in other tissues as well, up to and
including serious burns that may not be immediately evident
because of the tendency for microwaves to heat deeper
tissues with higher moisture content.

23. Don’ts
It is not safe to heat food in plastic bags, brown paper
bags, on paper towel, paper napkins or a colored
paper plate. All of these items can emit chemicals that
can migrate into food.
Microwaves provide a quick and convenient cooking
option however food is only safe to eat if the food
container used is designed specifically for heat.
Consumers should always use safe microwave
reheating information to ensure proper internal food
temperatures to prevent “cold spots” in your food
which are a haven for harmful bacteria.

24. If the empty container is cool it is microwave
safe; if it is slightly warm only use this container
for reheating. If the container is hot it is not
microwave safe and should not be used in the
microwave.
Be sure to remove food stored in take-out
containers, plastic cold-storage containers or on
a polystyrene tray and transfer to a microwave
safe container before reheating or cooking. Food
packaging containers are not safe for use in a
microwave as they were not designed for
exposure to heat

35. Chapter 3
Finding.1 Most of people prefer LG microwave.
Many people said that LG company microwave was the best. They
even voted for this company and advised me to buy this. They believed
that this company microwave consumed less amount of electricity which
was affordable by them. They even said that the features in the
microwave were good and easy to operate by anyone at their house.
They even added that the cost or price of microwave was also less that
was affordable by them. They even suggested me to buy this microwave
as it was small in size and got fitted in any small places.
LG Company provided them good services. They said that they
never needed to restore their microwave for many years. The food is
cooked very fast in the LG microwave. The LG Company gave them a
home delivery if ordered online which saved their money for transport. It
is very easy to operate the LG microwave by anyone in the house. They
never felt difficult to operate it at any time. This microwave never
shocked them at any time. It is safe to use and non-compromising too.So,
many suggested me to buy a LG microwave.

36. Finding.2 Many used conventional microwave
Many of the people said that convectional microwave cooked
their food evenly and made it crispy to have. They said that the
convectional microwave oven used a heating element and a fan to move
hot air around the oven which is equivalent to a regular oven but a bit
more efficient because the hot air helps to heat up all exposed parts of
the food and they got a more uniform heat.
They could easily baked cakes, fry crispy chips and snack in their
microwave without any problem safely. They insisted that buying and
convectional microwave would save a lot of money as it can bake, cook
and boil food items. The conventional microwave is good for the people
who always use it frequently. But it is also important to prepare crispy
food items. Even Indian can be cooked in this microwave. It takes less
time but it cooked the food evenly.
So, many of them asked me to buy the conventional type of microwave
where I can cook, bake and boil.

37. Finding3 Majority of the people voted for 50%-70% for the working of
microwave.
Many people voted for 50%-70% because they are not convinced
with the work of their microwave as they don’t use it more. Many people
go for an optional choice of cooking. It is using gas stove instead of a
microwave. Many people believe that microwave harms your health and
causes many diseases. Having a microwave they still keep it aside instead
of using it. Some people think that microwave consumes more electricity
and they go under loss and use a gas stove instead. Some people buy a
microwave to bake and cook snack items. But they don’t cook other food
items which forces them to rate 50%-70%. The microwaves usually
benefit the cake bakers and chips makers as they use it always. By using
the machine frequently they don’t get damaged quickly. So, they cake
baker use it a lot and rate it as 100%. So, most of the people rate 50-70%
for the working of the microwave oven. Therefore they asked me to buy a
microwave if it really helps me and even suggested me not to overuse it.

38. Finding.4 Most of the felt that automatic off was the best feature in
their microwave.
Many felt that automatic off was the best feature in their
microwave because they stated that their food was safely cooked even
after keeping the microwave ‘on’ for more time. The microwave gets
switched off automatically that benefits the user not to stay in front of
the microwave and look after it till it is off. Busy women or the people
no need to stay at the house to check whether the food is cooked or
no.
Automatic off prevents the food from getting burnt or over cooked. In
today’s generation people prefer easy methods of finishing. So,
automatic off is one of the feature in the microwave which makes the
works fast. If timer is set the food comes out cooked evenly where the
user no needs to guide it also. So, many of them prefer microwaves
having automatic off feature and even suggested me to buy this
microwave.

39. Finding5.Most of people prefer to cook Indian foods (roti) on stove not in
microwave.
Many people are unaware that Indian foods like roti can be cooked in
microwave. There is a feature in microwave that allows us to cook Indian
food on microwave. It cooks the chapatti or roti evenly and thoroughly. But
many people don’t know about it and are not familiar with it also. Instead
they prefer the traditional methods and long methods.
Some people think that rotis made in microwave will not taste good
and crisp like rotis done on the stove. They feel that the rotis on the stove
give them a good and bulged roti to have
But people can prefer to cook or roast rotis in microwave as the
microwave produces raditions that makes the food completely without
leaving any space uncooked. The heat produce on the normal tava on a gas
stove is exactly produced in the microwave. The heat is also even and oil also
can be adden in the beginning before roasting the roti.
But sometimes if the microwave is not turned off at a right time
the rotis can burn. But automatic off prevents it. Then there is no matter of
cooking rotis on gas stove. So, I suggest people to prepare chapattis and
rotis on microwave which gives a good roast.

40. Part A
To buy a microwave I will have to invest a
lot of money. The expenses are as follows:
I have to visit a showroom and I have to hire
a dealer that costs me Rs. 200-300.
As I wish to buy microwave pricing Rs.4500-
5500, I will have to invest money one the
microwave to buy it.
There are many accessories to buy with the
microwave. I’ll have to buy a stand for
microwave that keeps microwave safe. This

41. If I’ll have to buy a microwave to bake cakes
then I’ll have to buy a tray and moulds to
bake cakes. These together cost me around
Rs.1000-1500. After cooking the cooking
the as the food will be warm to hold. So, I’ll
have to buy a heating element that makes
keeps my hands safe without burning. It is
made with thick covers of cloth. It costs me
Rs.900-1000. I’ll have to Nordic microwave
slide worth Rs.600-700.

42. After the one year warranty I’ll have to
repair the microwave it damaged. Then
I’ll have to pay the laborer around
Rs.300. If any part is damaged I’ll have
to invest more than Rs.2000 as every
part in the microwave is costly.
After buying the microwave from the
showroom I’ll have to pay for the
transport around Rs. 100.

43. Part B
The total investment of the microwave will come from my bank
savings. The total cost of the microwave is:
Rs. 300 ----------- To hire a dealer
Rs. 5500-----------To buy a microwave
Rs. 500--------------To buy a microwave stand
Rs.1500--------------To buy micro-proof utensils and a baking
tray
Rs.600---------------To buy a heating element
Rs.700---------------Nordic slide
Rs.300--------------- labour
Rs.2000 (Optional) -------------- Damaged part
I’ll have to invest Rs.6,420 to buy a microwave. I decided to get
this money from my bank savings.

44. Conclusion
After a long journey of this project I would like to
conclude that LG is the more preferable company for
me to buy it. Its cost is less and also affordable. But
microwave really harm our health and is a slow
poisoning machine, although it cooks fast it even kills
fast. So, it will be better to use it in a limited quantity I
have decided not to overuse the microwave as it is a
threat for the health but use it only to bake and boil
food. I hope the people’s suggestions help me buy a
good company microwave as such.
