Optics Question 1113
In Young’s double slit experiment with a source of light of wavelength $ 6320\ \text{Å} $ , the first maxima will occur when
[Roorkee 1999]
Options:
A) Path difference is $ 9480\ \text{Å} $
B) Phase difference is 2π radian
C) Path difference is $ 6320\ \text{Å} $
D) Phase difference is π radian
Show Answer
Answer:
Correct Answer: B
Solution:
For maxima, path difference $ \Delta =n\lambda $ So for n =1, $ \Delta =\lambda =6320{AA} $
