The coherent formula for fringe visibility is

View answer and explanation

Correct option: A

V = \frac{{{I_{\max }} - {I_{\min }}}}{{{I_{\max }} + {I_{\min }}}}

Option A (

V = \frac{{{I_{\max }} - {I_{\min }}}}{{{I_{\max }} + {I_{\min }}}}

) is correct because this is the standard formula for calculating fringe visibility in interference patterns.
