Sound Waves
1. Require a medium.
2. Travel with a speed of 332 m/s at 0 C.
3. Are longitudinal waves consisting of compressions and rarefactions.
4. Are of different frequencies, giving notes of different pitches.
5. Do not travel far as their energy is dissipated easily.
Light Waves
1. Do not require a medium
2. Travel with a speed of 3 *108 m/s.
3. Are electromagnetic waves consisting of varying electric and magnetic fields.
4. Are of different frequencies, resulting in different colors.
5. Can travel through a much greater distance.

Sound is only a wave, whereas light exhibits both wave and particle properties.

– Sound is a longitudinal wave, but light is a transverse wave.

– Sound needs a material medium to travel, light can propagate through vacuum also.

– Light travels much faster than the sound.

Scientists have achieved the speed of sound, but still they are unable to go past the speed of light.

Sound has nearly the same characteristics of a wave. Sound works by transferring the energy(vibrations) to other particles. If we take a close look at sound, we would see that the particles oscillate back and forth. Sound has a speed of about 330 m/s and unlike light, sound cannot travel in a vaccum.

Light travels as transverse waves and can travel through a vacuum. Sound travels as longitudinal waves and needs to travel through a solid, liquid or gas: it cannot travel through a vacuum.

Light and sound can be reflected and refracted, just like water waves. Light and sound can also be diffracted, just like water waves, but diffraction in light is less obvious than in sound.

Table comparing light and sound waves

PropertyLightSoundType of wave | Transverse | Longitudinal
Can they travel through a vacuum? | Yes | No. Sound waves can only pass through a solid, liquid or gas
Can they be reflected? | Yes | Yes
Can they be refracted? | Yes | Yes
Can they be diffracted? | Yes | Yes
Can they interfere? | Yes | Yes

What is Wave Length?

Forms of electromagnetic radiation like radio waves, light waves or infrared (heat) waves make characteristic patterns as they travel through space. Each wave has a certain shape and length. The distance between peaks (high points) is called wavelength.

Propagation of sound in different mediums a
re-
In solids when we  knock table and a boy keeps on the table he other boy is able to listen to the knock done by the first boy.
In liquids when a bell is rung in the water we will be able to hear the bells sound.
In the gases it is really  easy for a sound to pass.

A compression is a region in a longitudinal wave where the particles are closest together.

A rarefaction is a region in a longitudinal wave where the particles are furthest apart.

Experiment to show sound in different medium
Take a cell phone a bell or any thing that makes a sound and ring it
In water the sound will be minimal but came be heard but In air it his heard clearly .

Air: Sound propagates through air as a longitudinal wave. The speed of sound is determined by the properties of the air, and not by the frequency or amplitude of the sound.
Liquid:

# data[].attributes.body
Because of the longitudinal motion of the air particles, there are regions in the air where the air particles are compressed together and other regions where the air particles are spread apart. These regions are known as compeessions and rarefactions respectively.

# data[].attributes.body
A compression is a region in a longitudinal wave where the particles are closest together.

A rarefaction is a region in a longitudinal wave where the particles are furthest apart.
All media have three properties which affect the behavior of sound propagation:

1. A relationship between density and pressure. This relationship, affected by temperature, determines the speed of sound within the medium.

2. The motion of the medium itself, e.g., wind. Independent of the motion of sound through the medium, if the medium is moving, the sound is further transported.

3. The viscosity of the medium. This determines the rate at which sound is attenuated. For many media, such as air or water, attenuation due to viscosity is negligible.

# data[].attributes.body
Sound is a sequence of waves of pressure which propagates through compressible media such as air or water. (Sound can propagate through solids as well, but there are additional modes of propagation). During their propagation, waves can be reflected, refracted, or attentuated by the medium.
