Question

If the speed of light is 3.0 ×108 m s-1, calculate the distance covered by light in 2.00 ns.

Solution

According to the question:

Time taken to cover the distance = 2.00 ns

= 2.00 × 10–9 s

Speed of light = 3.0 × 108 ms–1

Distance travelled by light in 2.00 ns

= Speed of light × Time taken

= (3.0 × 108 ms –1) (2.00 × 10–9 s)

= 6.00 × 10–1 m

= 0.600 m

  Is there an error in this question or solution?
