Question

1) On the plane mirror system shown here, if thefinalangle
of reflection for this ray is 14.0°, find the initial angleofincidence.

2)

A ray oflight is sent between parallel planemirrors, as shown.The raybarely misses the lower mirror as itenters the“corridor.” The mirrors' edges are aligned withoneanother, as shown. The mirrors are 3.00 cm apart, and each is18.0cm long. Find the smallest initial angle of incidence so thattheray…
(i)hits only the topmirror.
(ii)hits each mirror exactly once.

3) Why don't diamonds sparkle as much when viewedunderwater?Explain thoroughly,using words, equations and diagramsasnecessary.

4) A spherical mirror producesan image that is located 43.0 cmbehind the mirror when the objectis located 12.5 cm in front ofthemirror.

(i)What is the focal length ofthemirror? (ii)Isthis mirror concave orconvex?

5)A concave mirror (f= 54.0 cm) produces a real imagewhose distance from themirror is one-third of theobjectdistance. (i)Findtheobjectdistance. (ii)Findthe imagedistance.
