Question

If the velocity of light is 3.0 10 metres per second, calculate the distance travelled by light in a light year and express it in standard form [Hint: One light year = Distance travelled by light in a year

​

Answer 1

Answer:

Given :

Speed of light =3×10  

8

 ms  

−1

 

Times=2.00 nsec=2×10  

−9

 s

As we know,

Distance covered =Speed×time

The distance traveled is the product of speed and time.

Thus, in 2.00 nsec, the light will travel a distance of 3.00×10  

8

ms  

−1

×2.00×10  

−9

s=0.600m
