Question

Boojho saw a cracker burst at night at a distance from his house. He heard the sound of the cracker a little later after seeing the cracker burst. Give the reason for the delay in hearing the sound.

Answer 1

Sound:

A sound is a form of energy that produces a sensation of hearing in our ears.

Explanation:

1. Sound travels at a considerably slower rate than light.
2. Sound travels at a speed of around $300$ meters per second in air.
3. Whereas light can travel at a speed of three hundred million meters per second through a vacuum.
4. Light and sound travel at different speeds in several mediums.
5. The speed of light in air is equal to $3\times {10}^8\mathrm{m}/\mathrm{s}$.
6. The speed of sound in air is equal to $330\mathrm{m}/\mathrm{s}$.
7. The speed of sunshine is quicker than the speed of sound, therefore Boojho detected the sound of the cracker a touch later once seeing the cracker burst.
