Sim on electromagnetism by irene e. gonzales

PREFACE
In our modern world, Science is part of our culture and its input in our civilization is obvious and undisputed, boundless and
diverse. While other perceived the subject as exciting, still majority of the student find it difficult. Hence, few students from Lucena City
National High School feel the same towards the subject. Based from the result of the Second Quarter Examination, it was found out that
there are competencies which were not mastered. These include the competencies under S10FE-IIa-b-47; Compare the relative
wavelengths of different forms of electromagnetic waves, S10FE-IIc-d-48; Cite examples of practical applications of the different
regions of EM waves, such as the use of radio waves in telecommunicationsandS10FE-IIe-f-49;Explain the effects of EM radiation on
living things and the environment.
The Department of Education continues to find for alternative solutions in uplifting the low performance of the learners. In line
with this, it is the mission of the teacher to provide quality education for the learners and ensure that no one will be left behind. The use
of modules, self-learning kits and SIM, came to view as an alternative in exchange for usual classroom discussions.
This Strategic Intervention Material is an instructional material designed to promote strategic learning for students through the
help of self-learning activities intended for the specific learning competency. SIMs are conceptualized and designed to aid the teacher in
providing the pupils their needed support to make progress in studies. These will increase and deepen the skills, knowledge and
understanding of the learner in various subject areas not only in science but also in the various learning areas in the curriculum. It tends
to re-teach the lessons which are not clearer to the learners and help them gain mastery of the skills. Guide card, activity card,
assessment card, enrichment card and reference card are the basic elements of this kit. These cards were made engaging to ensure
that the low-performing students will enjoy and not be bored and continue to use it until the objectives are met.

TABLE OF CONTENTS

We believe that the world we live in is essential. Close your
eyes and think for a moment that this is not true. When it is dark, it
seems that the world does not exist because there is no light to
see. If you were a rattlesnake or an owl, you could see perfectly
well at night.
What if you were a Radar set mounted on an airplane?
Then, you could help pilots see in darkness or dangerous weather
by detecting reflected radio waves. If you were a camera sensitive
to X rays, you could even see through bodies or buildings!
Based on our past lesson, the light we can see is only one
part of all the electrical and magnetic energies buzzing around our
world. Radio waves, X rays, gamma rays and microwaves work in
a comparable way. Altogether, this energy is called the
ELECTROMAGNETIC SPECTRUM.
This Strategic Intervention Material will help you
understand better the different regions of Electromagnetic
Spectrum in a fun and easier way!
GOODLUCK and ENJOY!

There are two quantities which
are often talked when it comes to
EM waves. Wavelength (λ) and
frequency (ƒ). Wavelength (λ)is
the distance between two
successive crests or troughs,
while frequency(ƒ) is the number
of waves that come per second.
Welcome to Activity No.3. In this activity, you are going to arrange the different
EM waves according to the size of their wavelength from highest to lowest. Read the
information provided below as your guide.
Good luck!

Given the following frequencies, arrange the following EM waves according to the size of
the wavelength from highest to lowest.
a. microwave- 3 x 109

This is your first assessment. Fill in the blanks with the correct answers. Good luck!
The electromagnetic spectrum is consisting of 1. ____________________ different types of wave. The
one with the longest wavelength and lowest frequency is the 2. ____________________. This type of wave is
not visible, but we know it is there because we create transmitters to catch it. The next wave is
3. _________________, it still has a long wavelength and low frequency like radio wave, but it is used for something
different. This wave is used in cooking food and of course in 4. ____________________, and 5. __________________.
After that, come 6. ____________________. This type of wave is being used in remote controls of some toys and
household appliances. This wave is given off by hot objects including humans. Policemen use this wave through thermal
imaging equipment when they are tracking criminals.
The next part of the spectrum is the part we use in looking at objects. This is called 7. _____________.
This wave is given-off by any object that is hot enough to glow. A good example of this is the sun which has a
temperature of around 5600 degrees Celsius. The sun gives-off 8. ____________________ light which can be
separated into seven colors by using a prism. These colors are: Red, Orange, Yellow, Green, Blue, Indigo and
Violet.
The waves are becoming a little more dangerous. These three remaining waves are mainly used in
medical and sanitation purposes. These are 9. _____________________, X-Ray and 10. ________________.

Radio waves are the lowest frequency waves in
the EM spectrum. Radio waves can be used to carry
other signals to receivers that subsequently translate
these signals into usable information. Many objects, both
natural and synthetic emit radio waves.
Microwaves are the second lowest frequency
waves in the EM spectrum. Whereas radio waves can be
up to miles in length, microwaves measure from a few
centimeters up to a foot. Due to their higher frequency,
microwaves can penetrate obstacles that interfere with
radio waves such as clouds, smoke, and rain.
Microwaves carry radar, landline phone calls and
computer data transmissions as well as cook your
dinner.
Infrared waves are in the lower middle range of
frequencies in the EM spectrum, between microwaves
and visible light. The size of infrared waves ranges from a
few millimeters down to microscopic lengths.
Visible light waves let you see the world around
you. The different frequencies of visible light are
experienced by people as the colors of the rainbow.
Ultraviolet waves have even shorter
wavelengths than visible light. UV waves are the causes
of sunburn and cancer in living organisms. High-
temperature processes emit UV rays; these can be
detected throughout the universe from every star in the
sky.
X-rays are extremely high-energy waves with
wavelengths between 0.03 and 3 nanometers not much
longer than an atom. X-rays are emitted by sources
producing extremely hot temperatures like the sun's
corona, which is hotter than the surface of the sun.
Gamma waves are the highest frequency EM
waves and are emitted by only the most energetic cosmic
objects such as pulsars, neutron stars, supernova, and
black holes. Gamma rays can destroy living cells.
Fortunately, the Earth's atmosphere absorbs any gamma
rays that reach the planet.

Eating banana exposes you to about 0.1 micro Sieverts

The

This is why
Red should
