inclined at angle , to each other. Determine the deviation
produced by the reflections terms of . (3marks)
(b) Describe an accurate method for finding the focal length of a
(5marks) convex mirror.
A concave mirror forms a real image which is three times the
linear size of a real object. When the object is displaced through a
distance, x, the real image formed is now four times the linear size
of the object. If the distance between the two image positions is
20cm, find the
() focal length of the mirror. (3marks
