SATHEE: Optics Question 1047

Optics Question 1047

Question: Two waves have their amplitudes in the ratio 1 : 9. The maximum and minimum intensities when they interfere are in the ratio

[KCET 2002]

Options:

A) $\frac{25}{16}$

B) $\frac{16}{26}$

C) $\frac{1}{9}$

D) $\frac{9}{1}$

Show Answer

Answer:

Correct Answer: A

Solution:

$\frac{I_{max}}{I_{min}} = {(\frac{\frac{a_{1}}{a_{2}} + 1}{\frac{a_{1}}{a_{2}} - 1})}^{2} = {(\frac{\frac{1}{9} + 1}{\frac{1}{9} - 1})}^{2} = {(\frac{5}{4})}^{2} = \frac{25}{16} .$
