So we first want to find the scattering angle.
00:04
So we need to express compton shift.
00:08
Lambda prime minus lambda is equal to h divided by mc1 minus cosine theta.
00:13
And we need to apply the conservation momentum along the direction of collision.
00:18
So p .i is equal to pf.
00:20
So then we'll have h divided by lambda is equal to h divided by lambda prime cosine theta, plus eventually we get mv cosine theta.
00:29
So along the perpendicular direction, we have 0 is equal to h divided by lambda prime, sine theta, minus mv sine theta.
00:40
So we can rearrange our terms, and we'll get mv is equal to h divided by lambda prime.
00:45
And we can plug this into our original equation, and we'll get h divided by lambda is equal to 2h divided by lambda prime cosine theta...
