    Faraday Effect: Calculating Vedet Constants

    Hi guys, so we currently ran an experiment where we calculated the verdet constant when laser light passed through a glass rod then through an analyzer to a photodetector. The experiment worked great for us but I wanted to know if anyone has ever calculated the verdet constant for any other...

    Thermal Physics adiabatic and isothermal compressibilty

    Ok so I found something online but I need to understand this problem Prove that the ratio of the adiabatic compressibilty ks to the isothermal compressibility kr is equal to the ratio of the specific heat at constant colume, Cv, to that at constant pressure, Cp Definitions of the...

    Thermal Physics problem: Van der Waals

    i forgot a step, -2dT = (T/V)dV --> (-2/T)dT=(1/V)dV but i separated varibles by putting all T's and V's on opposite sides of the equation -(1/T)[2NkdT] = (1/T)[a(N^2)/(V^2) + NKT/V - (aN^2)/(V^2))/T)dV simplify a bit... 2NkdT = (NKT/V)dV 2dT = (T/V)dV (2/T)dT = (1/v)dV then integrate both...

    Thermal Physics problem: Van der Waals

    ok dU=(∂U/∂T)dT + (∂U/∂V)dV --> dU = 2NKdT + aN^2(1/V^2)dV I plug in P and dU into dS = (1/T)dU + (P/T)dV I get... dS = (1/T)[2NkdT + a(N^2)/(V^2)dV] + (NKT/V - (aN^2)/(V^2))/T)dV please correct me if I am wrong but since S is constant, then dS equals 0, therefore the lefthand side is 0, we...

    Thermal Physics problem: Van der Waals

    ok so thermodynamic identity --> dS=(1/T)dU + (p/T)dV

    Thermal Physics problem: Van der Waals

    I took a a snapshot of the problem to be more specific

    Thermal Physics problem: Van der Waals

    [b]1. Find an expression that relates T and V in a process in which the entropy S is constant, by doing the following: a) From thermodynamic identity dS=(1/t)dU + (p/v)dV find the expression for dS as a function of T and V (and dT and dV). b) Integrate the expression found in (a)...
