    Probability of penetrating a potential barrier

    I hadn't thought of that at all. I'll give it a try, thanks!

    Probability of penetrating a potential barrier

    I did that as part of the maths which led to the final inequality, I just didnt show the steps as its just rearranging the original inequality.

    Probability of penetrating a potential barrier

    Homework Statement The probability for a particle of energy E<<V0 to penetrate a potential barrier of height V0 and width d is approximately \frac{16E}{V_0}exp\left[\frac{-2d\sqrt{2m(V_0-E)}}{\hbar}\right]. An electron moves between two potential barriers of height V0 and 2v0 that are of widths...

    LIGO Homework Problem

    That actually makes more sense to me than how I interpreted it. I'll give that a try, thanks!

    LIGO Homework Problem

    Yeah that was my mistake, the power in the question is given as J/s not just J. It was more the method I was using to calculate the number of photons that I was questioning. It was the way that seemed logical to me however I have no solution to compare with. In regards to part (ii) I felt the...

    LIGO Homework Problem

    Homework Statement In-phase light from a laser with an effective power of 2x105J and a wavelength of 1064nm is sent down perpendicular 4km arms of the LIGO detector. (i) Determine the number of photons traveling in the interferometer arms. (ii) Assuming the detector is sensitive enough to...
