MCQ
The correct formula for fringe visibility is
  • ✓
    $V\, = \,\frac{{{I_{\max }} - {I_{\min }}}}{{{I_{\max }} + {I_{\min }}}}$
  • 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

Correct option: A.
$V\, = \,\frac{{{I_{\max }} - {I_{\min }}}}{{{I_{\max }} + {I_{\min }}}}$
a
Fringe visibility $(V)$ is given by

$V\, = \,\frac{{{I_{\max }} - {I_{\min }}}}{{{I_{\max }} + {I_{\min }}}}$.
