What Are The Similarities Between Sound Waves And Light Waves?

Sound waves are produced by compression and rarefaction of the particles of the medium. Sound waves are categorized as longitudinal waves. Light waves are transverse waves and also known as electromagnetic waves. There are three basic similarities between sound waves and light waves including interference, diffraction and refraction. Both the waves have the property of interference. When two coherent waves of sound waves or light waves fall in a same medium in a same direction, interference takes place. These waves when strike an opaque object, they diffract from their path. Sound waves and light waves have The property of refraction. When they pass from one medium to other medium, they refract from their original path.
