Boojho saw a cracker burst at night
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

reason for the delay in hearing the sound.

Solution:

The light travels faster than sound. So, the light from the cracker reaches faster than that of sound of the cracker.

Speed of light in air = 3 x 108 m/s

Speed of sound in air = 330 m/s
