Question: If L is the coherence length and c the velocity of light, the coherent time is
[MP PMT 1996]
Options:
A) cL
B) $ \frac{L}{c} $
C) $ \frac{c}{L} $
D) $ \frac{1}{Lc} $
Show Answer
Answer:
Correct Answer: B
Solution:
Coherent time $ =\frac{Coherence\ length}{Velocity\ of\ light}=\frac{L}{c} $
