Question

State two differences between the light and sound waves.

Answer 1

1. Sound is a longitudinal wave whereas light is a transverse wave.
2. Sound is mechanical wave whereas light is electromagnetic wave.
3. Speed of sound is less than speed of light wave. For example, in air, sound travels at approximately 333.1 m/s, while light travels at about 300000000 m/s.
4. Sound waves require a medium to travel while light waves do not require a medium to travel.
