They are inherently different on the basis that light is electromagnetic radiation. Hence red light (long wavelength) diffracts more than blue light (short wavelength). How is diffraction related to wavelength In short, the angle of diffraction is directly proportional to the size of the wavelength. The speed of sound in air is about 30 meters per second. We classically think of light as always traveling in straight lines, but when light waves pass near a barrier they tend to bend around that barrier and become spread out. The velocity of light waves through a vacuum is 2.998 x 10 8 m/s. Sound waves usually travel more slowly in solids than in gases. Light waves travels at much higher velocity as compared to sound waves. ![]() Sound waves are compressions and rarefactions that travel.

It is true that sound and light are alike only to the extent that they are both waves. A : To observe diffraction of light the size of obstacle/aperture should be of the order of 10-7m. Many behaviors of sound can be explained using a few.
