Q. Assertion :Only coherent light sources produce sustained interference. Reason: Coherent light sources emit lights of same wavelength and with a constant phase difference.

Q. The necessary conditions for a steady and stable interference pattern, produced by two sources of light, are,

(i)

two light sources must emit waves of equal frequency

(i i)

two point sources should have the same amplitude

(i i i)
