In an interference pattern, the ratio of intensity of two waves is \(\frac{9}{25}\), then the ratio of maximum intensity to minimum intensity is:
Answer & explanation
Correct answer: option 1
$\frac{I_{max}}{I_{min}} =(\frac{ \sqrt{\frac{I_1}{I_2} + 1}}{ \sqrt{\frac{I_1}{I_2} - 1}})^2 =( \frac{ \sqrt{\frac{25}{9} + 1}}{ \sqrt{\frac{25}{9} - 1}})^2 = 16:1$
