AI Thread Summary
The discussion focuses on calculating the phase difference between perpendicular and parallel polarization components using Fresnel's Rhomb. The user is unsure about the relevant equations and seeks guidance on deriving the polarization components and phase difference from Fresnel coefficients. They express a need for assistance in understanding the calculations involved. A link to a resource on Fresnel's Rhomb is provided for further reference. The conversation emphasizes the importance of understanding polarization in optics.

Homework Statement

alpha = 54.6 degrees

I need to calculate phase difference between E(perpendicular) and E(parallel) polarization components.

Homework Equations





The Attempt at a Solution



Problem is I don't know any relevant equations!
Can I get the phase difference from Fresnel coefficients somehow??
Or actually I don't know even how to get the polarization components calculated.

So if someone could point me to right direction it would be much appreciated!

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
