And how does that look? |
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.
