### finding frequency from Einstein's equation

How exactly in a problem would you find frequency when given momentum?

λ = h/p, then
λ = c/ν —> ν = c/λ gives you frequency.

λ = h/p
since p is given and h is a constant, you can solve for λ with that equation. Then you can solve for frequency using λc=v because you know λ and c is a constant.

plug in momentum to λ = h/p to find λ , then plug that into λ =hv to find v
