Please tell me which one is the right one and why it is I'm very bad at Chem , I'm barely passing

jfraser · Answer

you know the wavelength of one, and the frequency of the other.

You need to use the equation for electromagnetic waves $$c = \lambda * \nu$$ to find the wavelength of the second wave and compare it to the red wave
