As a result of interference of two coherent sources of light, energy is :
1 redistributed and the distribution does not vary with time
2 increased
3 redistributed and the distributed changes with time
4 decreased
Explanation:
: Interference of two coherent sources of light energy is redistributed and distribution does not very with time.

Which of the following is false for interference of light?
1 Coherence of the sources is an essential condition for interference
2 The minima of the interference pattern need not be of zero intensity
3 Interference simply redistributes light energy, without destroying any of it
4 The minima of the interference pattern must always be of zero intensity
Explanation:
: The minima of the interference pattern must always be of zero intensity. In the interference resultant intensity is maximum while at some other points it is minimum. Hence, option (d) is false statement.

A laser beam is coherent because it contains
1 waves of several wavelengths
2 incoherent waves of a single wavelength
3 coherent waves of several wavelength
4 coherent waves of a single wavelength
Explanation:
: LASER i.e. light amplification by stimulated emission of radiation. Laser beam is intense, monochromatic that is of the single wavelength, collimated and highly coherent.

To demonstrate the phenomenon of interference, we require two sources which emit radiations
1 of the same frequency and having definite phase relationship
2 of nearly the same frequency
3 of the same frequency
4 of different wavelength
Explanation:
: For interference to occur two sources of light must be coherent (i.e. with same frequency and having a constant phase different).
