Vedclass · Answer

(B) Diffraction is the phenomenon of bending of light around the corners of an obstacle or aperture of the size comparable to the wavelength of light.For diffraction to be significant, the size of the obstacle or aperture $(a)$ must be comparable to the wavelength $(\lambda)$ of the incident light.If the size of the obstacle is much larger than the wavelength, the light appears to travel in a straight line (rectilinear propagation).Therefore, the diffraction effect depends on the size of the obstacle $(a)$ and the wavelength $(\lambda)$ of the light used.
