Question

Distinguish between sound waves and light waves.

Accepted Answer

Parameter

Sound waves

Light waves

1. Nature

These are mechanical waves.

These are electromagnetic waves.

2. Medium

These waves cannot travel through vacuum. They always require some material medium for their propagation.

These waves can travel even through vacuum.

3. Speed

These waves travel in air at a very low speed of $332 m s^{- 1}$ at $20 ° C$ .

These waves travel at very high speed of $3 \times 10^{8} m s^{- 1}$ in air.

4. Sensation

These waves produce the sensation of hearing.

These waves produce the sensation of sight.

5. Type

These are longitudinal waves.

These are transverse waves.

6. Production

These are produced due to the vibration of the particles of the concerned medium.

These are produced due to the varying electric and magnetic fields.

7. Frequency and wavelength

These have low frequency and long wavelength.

These have very high frequency and short wavelength.

8. Effects of temperature

Their velocities change with the change in temperature, humidity, etc.

Their velocities do not change with the change in temperature, humidity, etc.
