1. A ray of light passes from air through dense flint glass and then back into air. The angle of incidence on the first glass surface is 63.5°. The thickness of the glass is 4.26 mm; its front and back surfaces are parallel. How far is the ray displaced as a result of traveling through the glass?
this is what I tried...
1sin65.5=1.6sinA
sinA=0.5593
A=34.01°
x=4.26tan63.5°-4.26tan34.01°
= 5.671mm
I am no sure where i did wrong...
