Question

how long does it take light to travel 1.0 m????????? ​

Answer 1

Answer:

1/300000000 seconds=3.3 nanosecond

Explanation:

By unitary method,

300000km------>1 second

=>300000000m------>1second

=>1m ------->1/300000000 second

Answer 2

Answer:

The Time taken by the light to travel 1 meter is (33.33) ( $10^{-10}$ )  seconds

Explanation:

Speed of light  (c) in the vacuum is taken as  (3)($10^{8}$) m/s.

The light is a wave hence its speed varies through a different mediums.

Here, in the question we assume that the light is travelling in a vacuum.

We know that,

Speed = $\frac{distance}{time}$.

Hence, the time (t) taken by the light to travel 1.0 meter in the vacuum;

time taken =( $\frac{1}{3}$ ) $10^{-8}$ = (33.33) ( $10^{-10}$ )  seconds.
