PhysicsEasysingle choice

The ratio of intensities of two waves producing interference is $9 : 4$ , then the ratio of the resultant maximum and minimum intensities will be $(cos \frac{π}{3} = \frac{1}{2})$

Options:

Answer:

Solution:

$\frac{I _{1}}{I _{2}} = \frac{9}{4}$ $∴ \frac{a _{1}}{a _{2}} = \frac{3}{2}$ $\frac{a _{1} + a _{2}}{a _{1} - a _{2}} = \frac{3 + 2}{3 - 2} = \frac{5}{1}$ $∴ \frac{( a _{1} + a _{2} ) ^{2}}{( a _{1} - a _{2} ) ^{2}} = \frac{25}{1}$
