Are light and sound on the same spectrum?

Light and sound are not on the same spectrum. Light belongs to the electromagnetic spectrum but sound does not. There are many types of light (infra red, ultra violet, visible light), all of which are electromagnetic waves and are therefore part of the electromagnetic spectrum. read more

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 (e.g. air) to travel through. read more

The spreading into rays was called dispersion by Newton and he called the different coloured rays the spectrum. He learnt that when the light rays were passed again through a prism the rays turned back into white light. read more

No, they are not "different bands of the same spectrum". If you really didn't know this, your knowledge of the physics of the real world is of a insufficient and meager nature. -=- Sound is a compression wave in matter. Light is energy of the electromagnetic spectrum. read more

* The entire visible spectrum is barely a factor of 2 in frequency, whereas the audible spectrum ranges over a factor of 1000 (20 Hz to 20 kHz). So you might have to arbitrarily restrict the frequencies and/or use quite different materials in different frequency ranges. read more
