What happens to the interference pattern the two slits S₁ and S₂ in Young’s double experiment are illuminated by two independent but identical sources?

Two sources of light are said to be coherent when both give out light waves of the same:

A single slit diffraction pattern is obtained using a beam of red light What happened the red light is replaced by the blue light?

For sustained interference, we need two sources which
emit radiations :

Which of the following is conserved when light waves interfere?

The application of Doppler effect are:

What is the reason for your answer to the above question?

In Young double slit experiment, a minimum is obtained when the phase difference of the superposing waves, is (n ∈ l):

The angle of minimum deviation of a prism depends upon the aggie of:

What happens if one of the slits, say S₁ in Young’s double , slit experiment-is covered with a glass plate which absorbs half the intensity of light from it?

The minimum value of the refractive index is:

When a polaroid is rotated, the intensity of light varies but never reduces to zero. It shows that the incident light is:

The theory of expanding universe is confirmed by the observation of the spectral lines of the star, which shows :

The intensity of light emerging from the two slits, in Young’s experiment is in the ratio 1 : 4. The ratio of the intensity of the minimum to that of the consecutive maximum will be:

Poisson’s bright spot was discovered by:

When a polaroid is rotated, the intensity of light does not vary. The incident light may be:
