Question

what is the essential condition for diffraction of wave?

Answer 1

Answer:

Diffraction occurs when we pass a light through a orifice of small aperture. ... It is the most essential condition for the diffraction to occur. The opening or slit width has to be comparable or less than the wavelength of light for prominent diffraction patterns.

Answer 2

$\huge{\underline{\bold{\orange{❥︎ANSWER}}}}$

Diffraction is a phenomenon that occurs when light comes across an object and is obstructed. The essential condition for diffraction to occur is that the wavelength of light should be comparable to that of the size of the object. It might also occur if the size of the object is less than the wavelength of light.
