This slide is prepared for the students of class nine to teach digitally to make learning fun. First I uploaded sound slide in nepali but found some font problem. So i prepared in english medium as well.
Complete and comprehensive study of the entire chapter with attractive pictorial representation of topic being discussed and Studied. Ideal material for students to get a gist of the entire Chapter, make projects, complete ppt slide presentation for self study and group discussion.
Sound waves are produced by the vibration of material objects. A disturbance in the form of a longitudinal wave travels away from the vibrating source. High-pitched sounds are produced by sources vibrating at high frequency, while low-pitched sounds are produced by low-frequency sources Sound waves consist of traveling pulses of high-pressure zones, or compression, alternating with pulses of low-pressures zones, or rarefaction. Sound can travel through gases, liquids, and solid, but not through a vacuum.
Thanks all. I am from chiranjiv bharati school, palam vihar. this presentation is on sound and covers various other topics like frequency, wavelength, Sonar, types of sound, etc.
A powerpoint explaining what sound waves are, the equation used to calculate displacement, the equation used to calculate pressure and the equation for intensity.

we hear many type of sound from various sources like humans, birds, bells, machines, vehicles, televisions, radios, etc. Sound is a form of energy which produces a sensation of hearing in our ears.
The presentation which increases your knowledge about sound.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

Honest Reviews of Tim Han LMA Course Program.pptxtimhan337
Personal development courses are widely available today, with each one promising life-changing outcomes. Tim Han’s Life Mastery Achievers (LMA) Course has drawn a lot of interest. In addition to offering my frank assessment of Success Insider’s LMA Course, this piece examines the course’s effects via a variety of Tim Han LMA course reviews and Success Insider comments.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
5. Sound is the form of energy
Introduction of sound
Sound gives the sensation of hearing
Sound is produced due to the vibration of the particles present
in the body
The object should vibrate to produce
sound
6. sound energy propagates from one palce to
another in the form of wave
t
Sound can propagate in
solid,liquid and gas medium
Material Medium is required to propagate
sound from one place to another place
7. Sound wave is a
longitudinal wave
1
Sound wave is a mechanical wave
because it needs material medium to
propagate
2
The region where the density
of particle is maximum is
Compression
3
The region where the density
of particle is minimum is
Rarefaction.

Sound wave+
11. In longitudinal wave the
direction of propagation of wave
and the direction of vibration of
particles are same
This wave can propagate in
solid, liquid and gaseous
medium.
sound wave, primary wave of
earthquake etc
In transverse wave the
direction of propagation of wave
and the vibration of the particles
are perpendicular to each other
This wave can propagate only
in solid and liquid medium
Water wave, secondary wave of
earthquake etc
12. Frequency is the number of
complete cycle in 1sec
The time taken to make
one complete cycle
wave length is the distance
between two successive
crests and troughs
It is the maximum distance
moved by the vibrating body

18. It is the prolongation of the
sound after mixing with original
sound
The distance between the
source of sound and reflecting
surface should be lesser then
17m
The speed of reverberation is
greater then original sound
It is the repetitions of the sound
after striking on the reflecting
surface
The distance between the
source of sound and reflecting
surface should be greater then
17m
The speed of echo is lesser then
the original sound
19. To detect the
position of weapons

To determine depth of
the sea
To determine the
position of baby in
the worm
In medical to
identify tumors,
stones etc
Importance of reflection of sound
20. The process of bending of sound waves when traveling from one medium to another medium is
called refraction of sound.
Refraction of
sound in day
Refraction of
sound in night
21. The distance travelled by the sound wave per
unit time is called speed of sound
Its SI unit is m/s
Speed of sound = f x λ
