Question

A beam of light has a wavelength of 506 nanometers. What is the frequency of the light? What color is the light?

Answer 1

I found: `5.9xx10^14Hz`, Cyan.

Explanation:

You can find the frequency `nu` from:
`c=lambda*nu`
where:
`lambda=506xx10^-9m` is the wavelength;
`c=3xx10^8m/s` is the speed of light in vacuum.
So:
`nu=c/lambda=(3xx10^8)/(506xx10^-9)=5.9xx10^14Hz`

It should be Cyan (`506 nm`):
