Question

If velocity of sound is 300 m/s then time take taken to travel a distance equivalent in light in 1 sec is

Answer 1

velocity of light = 3 * 10^8 m/s

distance travelled by light = 3 * 10^8 m/s  * 1 sec = 3 * 10^8 m

velocity of sound = 300 m/s

distance travelled by sound = 300 m/s * 1sec = 300m

Equivalent distance = Distance(sound)/ Distance(Light) = 3*10⁻⁶
