If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

Vedclass · Answer

(A) Diffraction is a general characteristic of all types of waves,including mechanical (like sound) and non-mechanical (like light),as well as transverse and longitudinal waves. Thus,the Assertion is correct.For diffraction to be significant or perceptible,the size of the obstacle or aperture must be of the order of the wavelength of the wave. If the wavelength is much smaller than the obstacle,the wave behaves like a ray and diffraction is negligible. Thus,the Reason is also correct and explains why diffraction is observed in specific conditions. Therefore,the correct option is $A$.

Assertion : Diffraction takes place for all types of waves,mechanical or non-mechanical,transverse or longitudinal.
Reason : Diffraction effects are perceptible only if the wavelength of the wave is comparable to the dimensions of the diffracting device.
