Question

The correct formula for fringe visibility is

• A. $V=\frac{I_{\max }-I_{\min }}{I_{\max }+I_{\min }}$
• B. $V=\frac{I_{\max }+I_{\min }}{I_{\max }-I_{\min }}$
• C. $V=\frac{I_{\max }}{I_{\min }}$
• D. $V=\frac{I_{\min }}{I_{\max }}$

Answer 1

Answer: (A)

Fringe visibility $(V)$ is given by,
$V=\frac{I_{\max }-I_{\min }}{I_{\max }+I_{\min }}$
