Explain briefly. 2. Write or choose the right wordsA prism behaves like a perfect mirror if light rays are incident on its ________ (inside/outside) face at an angle greater than the ________. However, they do not from ______ images as plane mirrors do.
1a) Let c be the critical angle for the glass-water interface, then sin c = 1.33/1.6 = 0.83125 c = 56.23 b) No, since total internal reflection only occurs when light goes from optically denser medium to optically less dense medium. 2) inside, critical angle, laterally inverted
