Optics Question 1031

Question: Ratio of amplitude of interfering waves is 3 : 4. Now ratio of their intensities will be

[RPET 2000]

Options:

A) $\frac{16}{9}$

B) 49 : 1

C) $\frac{9}{16}$

D) None of these

Show Answer

Answer:

Correct Answer: C

Solution:

$I \propto a^{2}$

$\Rightarrow \frac{I_{1}}{I_{2}} = {(\frac{a_{1}}{a_{2}})}^{2}$

$= {(\frac{3}{4})}^{2} = \frac{9}{16}$
