Wavelength question

[chs724]

Does someone know if wavelength could interfere each other or are they always additive?

What i mean by that would it be possible that too much wight light might overlap blue light for example? Sry if it might be dumb but i am new to this tropic.

Thx

You can have too much light, but light doesn't interfere to make less light in a reef aquarium.

Light can interfere with itself constructively and destructively. If two photons of the same frequency are 180 degrees out of phase they will cancel each other out.

In practice this is completely negligible especially when dealing with broad spectrum light from a noncoherent source.
