Diffraction of light Diffraction of light is the phenomenon of bending of light round corners of an obstacle or aperture and spreading into the geometrical shadow of the diffracting object. The condition for diffraction of light is the size of the aperture should be comparable to the wavelength of incident light. so in daily life, we find that diffraction of sound is more common than the diffraction of light. width of central maxima is {formula= ((2lambdaD)/d) } Two student are separated by a 5 m partition wall in a room that is 10 m high. if both light and sound waves bend around obstacles, we find that the students are unable to see the each other even though they can converse easily. it is due to
