What happens to the interference pattern the two slits S 1 and S 2 in Young's double experiment are illuminated by two independent but identical sources?

No interference pattern is observed

The intensity of the bright fringes doubled

The intensity of the bright fringes becomes four times

Two sets of interference fringes overlap

No interference pattern is observed

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

There is not constant phase difference between the waves emitted by the two sources

The two sources do not emit light of the same wavelength

The two sources emit waves which travel with different speeds

The two sources emit light waves of different amplitudes

There is not constant phase difference between the waves emitted by the two sources

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

Diffraction fringes become narrower and crowded

There is no change in diffraction pattern

Diffraction fringes become narrower and crowded

Diffraction fringes become broader and farther apart

The diffraction pattern disappear

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

having a constant phase difference

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

wavelength and a constant phase difference

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 bright fringes become less-bright and the dark fringes have a finite light intensity

The bright fringes become brighter and the dark fringes become darker

The fringe width decreases

No fringes will be observed
