Hey , I need some indication to solve this problem:
A ray light impinges at a 60 degres angle of incidence on a glass pane of thickness 5mm and index of refraction of 1.54.
the ligth is reflected by a mirror that touches the back of the pane. By how much is the beam displaced compared with the return path it would have if the pane were absent?
I found the angle x normal with the refracted ray. x= 34.2 degres.
I also found the length of the ray entering in the glass (up to the mirror)L= 5.10^{3}\ cos(x)=6.0 10^{3}m
From here what can I do to find the displacement?
I attach a picture of the problem.
Thank you
