Question

In a Michelson interferometer, one fringe shift corresponds to a mirror displacement of

• A. \(\lambda\)
• B. \(\dfrac{\lambda}{2}\)
• C. \(\dfrac{\lambda}{4}\)
• D. \(2\lambda\)

Hint:

For a Michelson interferometer, \[ \boxed{ 2d=m\lambda } \] For one fringe shift (\(m=1\)), \[ \boxed{ d=\frac{\lambda}{2}. } \]

Answer 1

The Correct Option is B
