Boojho saw a crac

Answer :

Boojho heard the sound of cracker after seeing the cracker because:

⇒ The speed of light is faster than sound.

Speed of sound in air = 330 m/s

Speed of light in air = 3 × 10⁸ m/s

⇒ Thus, Boojho saw burst of cracker (light) first, then after some times, he heard the sound.
