We live in a world surrounded by sound from nature and technology. Sound is used in fields like geology, oceanography, and healthcare to determine depths and for medical purposes. In physics, sound is defined as a mechanical wave involving oscillations of pressure that can travel through solids, liquids, or gases. It is a form of energy transmitted through vibrating matter that moves in waves.

2. Let as just first start at the basic.
We live in a world of sound.
Anywhere we go and whatever
we do, we hear sound.
We hear the chirping of birds,
ticking of clock and beating of our
hearts.

3.  Most of our gadgets are sound
embedded to
amuse us.
 In the field of geology and
oceanography, sound is used to
determine depths.
 The health sciences are also using
sound for medical purposes.
 Some animals are dependent on sound
for
movement.

4. IN PHYSICS,
Sound
• is a mechanical wave that is
an oscillation of pressure
• is transmitted through a solid,
liquid, or gas
• is a form of energy and is
transmitted by vibrating matters
• travels in waves

5. Sound is made when something vibrates.
• The vibration
disturbs the air
around it.
• This makes changes
in air pressure.
• These changes in
air pressure move
through the air as
sound waves.
