Sound and Light II

Light and sound can be reflected and refracted, just like water waves. Light and sound can also be diffracted, just like water waves, but diffraction in light is less obvious than in sound. Light and sound both travel in waves, but not of the same type. Visible light is part of the electromagnetic spectrum, and can therefore travel through a vacuum. Sound propagates as a longitudinal wave, and needs a medium to travel through – such as air.
