Sound travels at a significantly slower rate than light. Sound travels at a speed of around 330 metres per second in air. Light will travel at a speed of 300 million metres per second through the vacuum. Light and sound travel at different speeds in different mediums.
Speed of light is faster than the speed of sound, hence Boojho heard the sound of the cracker a little later after seeing the cracker burst.
- Speed of light in air = 3 x 108 m/s
- Speed of sound in air = 330 m/s
