S. L. Arora Solutions for Chapter: Wave Optics, Exercise 4: Problems For Practice

Two coherent sources, whose intensity ratio is $16:1$ produce interference fringes. If the ratio of intensity of maxima and minima in the fringe system is $\frac{25}{3\alpha }$. Find value of  $\alpha .$

The two slits in Young's experiment have widths in a ratio $25:1$. The ratio of light intensity at the maxima and minima in the interference pattern is $9:x$. Find $x$.

Light waves from two coherent sources have intensities in the ratio of $4:9$. Find the ratio of intensities of maxima and minima in the interference pattern.

The ratio of intensity at maxima and minima is $25:16$. The ratio of the width of the two slits in Young's double slit experiment will be _____ : $1$.

Two coherent sources whose intensity ratio is 81:1 produce interference fringes. The ratio of intensity of maxima and minima in the fringe system is _____ : $16$.

The width of one of the two slits in a Young's double slit experiment is double of the other slit. Assuming that the amplitude of the light coming from a slit is proportional to the slit width, ratio of the maximum to the minimum intensity in the interference pattern $x:1$. Value of $x$ is
