We are given a figure of a half-cylinder with a point a at the top of the half cylinder. Light is transmitted through a half cylinder and the beam was allowed to strike a semi-circular screen.
Question asks : Light that initiates from point a in the figure:
A- will always strike the middle of the screen
B- doesn't leave the half-cylinder disk
C- splits to strike the screen at multiple points
D- slows when leaving the disk and entering air.
Answer is A which does not make sense to...
TBR light that hits an interface in a perpendicular fashion
