Question

Calculate the distance covered by light in 2.00 ns

Answer 1

Answer:

speed of light for 1sec=3×10^8m/sec

⇒for 1sec=distance is 3×10^8 m

for 2ns=2×10^-9sec=xm

⇒xm = (2×10^-9sec×3×10^8m)1sec

xm = 0.6m

⇒for 2.00ns light covers 0.6m

Answer 2

Answer:

dist covered by light in 2 nano second..

i.e., 2×10^-9 sec

now, distance=speed × time

distance=3×10^8 × 2×10^-9 m

= 0.6m
