Homework Statement
A beam of neutrons (m=1.675x10-27kg) is incident on a nucleus. Consecutive transmission maxima are observed for beam energies of 1.15, 23.656, and 50.254 MeV. Treating the nucleus as a one-dimensional square-well potential:
(a) What is the width of the potential? (ans. 10...
Oh, I thought it was a y. Regardless, you can just say
tanθ=y/x tanθ'=y'/x'
(tanθ)/(tanθ')=yx'/xy'
but since y=y'
(tanθ)/(tanθ')=x'/x
xtanθ=x'tanθ'
so then use
tanθ'=tanθ/√1-V2/c2
plugging in the numbers gives me θ'=43.9, which is the answer in the book.
please let me know if my...

A meter stick is at rest in the laboratory frame. It lies in the x-y plane, making an angle of 30° with the x-axis. What angle does this meter stick make with the x'-axis of a reference frame moving at V=0.8c in the x-direction.
Laboratory frame is the rest frame...
