Question

Light travels at a speed of 3 X 10 ^(8) m / s . Find the distance covered by light in 1 year.

Answer 1

Answer:

time = distance / velocity.

distance = 1.5x10^11m

velocity = 3.0x10^8 m/s

Substituting into the equation:

time = (1.5x10^11m)/( 3.0x10^8 m/s) = 500 seconds

Therefore, light travelling at 3.0x10^8 meters per second takes 500 seconds (8 minutes, 20 seconds) to reach the Earth, which is 1.5x10^11 meters away from the sun.
