The wavelength of green light is 550 nm. If an electron has the same wavelength, determine the electron velocity and momentum. (b) Repeat part (a) for red light with a wavelength of 440 nm. (c) For parts (a) and (b), is the momentum of the photon equal to the momentum of the electron?

Yes

Explanation:

Because using Broglie formula of lambda=h/mv,

velocity v=h/(m x lambda).

So the momentum of the photon of light will also use p=h/lambda resulting in the same momentum for each part a and b

whichever one it is, it's definitely not one that you included on the list you provided.
