Explanation
Two coherent sources of intensity ratio \beta interfere. Then the value of \displaystyle \left( {\frac{{{I_{\max }} - {I_{\min }}}}{{{I_{\max }} + {I_{\min }}}}} \right) is:
Correct option is : (D) All kind of waves
\bulletInterference occurs in all kinds of waves, pattern depending upon the phases of the interfering waves.
\bulletInterference in longitudinal waves occurs in sound waves.
\bullet Interference in transverse mechanical waves occurs in water ripples.
\bullet Interference in transverse non mechanical waves occurs in light.
