Different colors have different wavelengths, and therefore have different diffraction angles. For example, using a non-monocromatic laser and a mirror to cause diffraction we can separate each wavelength (color) of the laser beam:
On the right figure, blue is on the left and green is on the right, no matter if you can't differentiate the colours, or see them different. Instead of doing that, we can use different monocromatic lasers (one red, other blue, yellow, etc), each one will suffer diffraction at a different angle.
So we can help somebody to differentiate between colors, but we can't explain how blue "looks like" to someone who never have seen it. |
I appreciate the illustrations on the properties of light, if I remember my physics correctly yes white light diffracts at different angles through a medium of one density (eg air) to another density (eg glass prism) revealing the spectrum of light due to the different wavelength and frequencies they have, anyway your picture demonstrates it better.
But it is the last part of your post I am addressing why is it we cannot explain what it looks like.
