Light exhibits wave nature because...

If two sources emit light waves of different amplitudes, then in the interference pattern:

The phenomenon of interference is based on

For the constructive interference,the path difference between the two interfering waves must be equal to:

$A$ 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

In an interference experiment,the ratio of amplitudes of coherent waves is $\frac{a_1}{a_2} = \frac{1}{3}$. The ratio of maximum and minimum intensities of fringes will be
