The intensity of light depends upon:

In an interference pattern obtained by two coherent sources,the variation in intensity is $5\%$ of the average intensity. Find the ratio of the intensities of the two sources.

Two coherent waves of intensities $I_1$ and $I_2$ produce an interference pattern. The maximum intensity of the interference pattern is .....

$A$ ray of light from a monochromatic point source of light is incident at a point on the screen. If a thin mica film of thickness $t$ and refractive index $n$ is introduced in its path,then the optical path

The frequency of a light wave with a wavelength of $500 \, \mathring A$ is $....... \, Hz$.

Intensities of the two waves of light are $I$ and $4I$. The maximum intensity of the resultant wave after superposition is (in $I$)
