Answer 1

Photons have a wavelength, or a frequency, depending on how you want to look at it.

In your eyes are “rods and cones” which are sensitive to photons of certain wavelength ranges. Those are what we call colours. You have red, green, and blue cones (unless you have colour blindness or such) which react to those colours and you see things with them.

All things considered, it’s a fairly specific range of wavelengths/frequencies we can see.
