Question:

Under what conditions would the reflectance R and the transmittance T be equal to each other at normal incidence at an interface? What would be the values of R and T under these conditions?


Answers

Reflection co-efficient for perpendicularly polarized light- E n, cos (e)-n, cos e cos ( ?) + n, cos ?, Transmission co-efficient- cos(@))+n, cos @, 2n, cos ? -n,cos(e)+n,cos ? These equations are Fresnels equations for perpendicularly polarized light Reflection co-efficient for parallel polarized light n,cos(8)-n E n,cos(e)+n,cos e Transmission co-efficient- ncos(e)- cose cos(6)n, cos e, n, cos(e)+n cos e These equations are Fresnels equations for parallel polarized light For both polarizations, The two polarizations are same at ?-0. Values of R and T- R-reflected power/Incident power RA-area Since the angle of incidence -angle of reflection, the area of the beam doesnt change on reflection.
