Homework Statement
Calculate the deBroglie wavelength of a proton moving at 1/4 the speed of light.
How does the kinetic energy of this proton compare to its p^2 /2m?
What does p^2 / 2m anyway conceptually (isn't it one of the triangle thingies in the lower version of E=mc^2)?
Homework Equations
deBroglie equation
The Attempt at a Solution
hf = KE + phi
lambda = h/mv
v = 0.25c, m = proton
that calculates lambda
then lambda = c/f to find frequency ...but i don't know how to find KE. (is it just 1/2mv^2?)
