Assertion : All bright interference bands have same intensity.
Reason : Because all bands do not receive same light from two sources.

Assertion : Intensity pattern of interference and diffraction are not same. Reason : When there are few sources of light, then the result is usually called interference but if there is a large number fo them, the word diffraction is more often used.

Assertion:In beta- decay, all the emitted electron do not have the same energy. Reason: beta- decay is not a two body decay process.

In interference of light, bright bands occur on the screen at

Both in interference and diffraction phenomena, alternate dark and bright fringes are obtained on screen i) generally fringe width is same in interference and not same in diffraction ii) the central fringe in interference has maximum brightness and thei intensity gradually decreases on either side iii) in interference the intensity of all bright fringes in same iv) both the phenomena are produced from same coherent sources
