Homework Help: Compton shift

    I have a problem saying:

    X-rays having an anergy of 300KeV undergo Compton scattering from a target. The scattered rays are detected at 37 degrees relative to the incident rays. Find the (a) Compton shift at this angle.

    Now i have the angle.. but i figure i need the wavelength of the X-ray. How do i get that?

    p.s. still in intro classes :D

    E = h (nu)... does that look familiar?

    If it was in an intro E/M course... then no lol

    There's a formula equating the energy to the frequency multiplied by a constant, "h". The frequency has a really close relation to the wavelength.

    So, what, Energy = plancks constant * (nu)? Whats nu?

    greek letter that's used for a symbol for "frequency"

    Haha gold, always nice to know my brain just shut itself off while overlooking E=hf (found it in the same chapter i was doing problems from).

    Is the frequency 7.25 x 10^19?

    Ok ok it looks right i hope :D. So now it asks

    (b) Find the energy of the scattered x-ray

    Is that the E=hf ???
