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...

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

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?

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 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}}

Awesome, Cheers man

Actuallty what I am looking at is the temperature dependacy of the specific heat capacity

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

upon recent studies of the Density of states and Specific heat capacities, I've found the einstein 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...

Ok. I am having trouble identifing the saturatoin field on the Hysteresis Loop. How do I find it?Also the initial and maximum relative permeability. Is the maximum relative permeability infinte?

Gza The Genius. Chemistry is a branch of Physics. Physics is the OG.

This is correct

Yea thanks i already know what a TOE is and the four fundamental forces are thanks ne way

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...

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
