    Solving Light Refraction Boundary Conditions: Find T^-1

    Can someone please help me with this question: Light with frequency \omega in media 1 ,with refractive index n_{1} , is incident (normal) to an interface of media 2, with refractive index n_{2}, and then is incident on a second interface with refractive index n_{3}. Using boundary conditions...

    What is the relationship between the period and length of a pendulum?

    Not quite period goes as sqrt{L} i.e increasing the length by 4 increases the period by 2

    How to Calculate Reflection Coefficient for Light at Air to Silver Interface?

    eta_s is the impeance of silver. As indicated previously a value with ohm units can be achieved by combining wavelength with the value of conductivity. What I am asking is, is this a valid statement?

    How to Calculate Reflection Coefficient for Light at Air to Silver Interface?

    Would this work? Knowing the frequency means we can find the wavelength clearly, which has units metres, clearly. When combined with \sigma = {6 * 10^7 mhom^{-1}} to get the impedance of the silver. Then taking the ratio with the impedance of free space and assuming normal incidence r...

    How to Calculate Reflection Coefficient for Light at Air to Silver Interface?

    How does one calculate the reflection coefficient for light at an air to silver interface at optical frequencies (\omega = {4 *10^{15} s^{-1}}) given \mu_{I} = \mu_{T} = \mu_{0} , \sigma = {6 * 10^7 mhom^{-1}}

    Understand Nuclear Scattering - Can Anyone Explain?

    Im not too clear on how the scattering process may be used to probe the excitaion structure of the nucleus. Can anyone explain this to me or direct me to somewhere in which i can read about it? Cheers

    Density of States: Debye vs Einstein Models & Realistic Findings

    upon recent studies of the Density of states and Specific heat capacities, I've found the Einstien and Debye Models to be very helpful, Debye being the more accurate of the two models at low temperatures as it takes into account the low frequency modes. However, the realistic density of states...

    M-Theory is a theory which 'combines' the five superstring theories

    Waddup guys. To my understanding M-Theory is a theory which 'combines' the five superstring theories and supergravity.Also i understand that matematics is not yet advanced enough to make it work(or so I've been told) I am still not sure how this theory is meant to end up as a theory of...

    Is There a Center to the Universe?

    Ok. It was once said tht the universe is infinitly big. If this is so then it is impossible to define a centre. Thats just one theory
