Question

Difference between a light wave and sound wave

Answer 1

Answer:

There are many differences between light waves and sound waves

1) Sound waves travel through air at the speed of approximately 1,100 feet per second whereas light waves travel through at the speed of approximately 186,000 miles per second.

2)Although both are forms of wave motion, Sound requires a solid, liquid, or gaseous medium whereas light travels through empty space or vacuum

Answer 2

Answer :-

↦ LIGHT WAVE :

• Light waves can travel in vaccum.
• Speed of light in air is 3 × 10⁸ m/s.
• Light waves are transverse electromagnetic waves.

↦ SOUND WAVE :

• Sound waves cannot travel in vaccum.
• Speed of sound is 330 m/s.
• Sound waves are longitudinal mechanical waves.
