Question 210: Ray Optics

Question

If two mirrors are kept at $${60^ \circ }$$ to each other, then the number of images formed by them is

Accepted Answer

KEY CONCEPT :
When two plane mirrors are inclined a each other at an angle $$	heta $$ then the number of the images of a point object placed between the plane mirrors is
$${{{{360}^ \circ }} \over 	heta } - 1,\,\,if{{{{360}^ \circ }} \over 	heta }$$ is even
$$	herefore$$ Number of images formed
$$ = {{{{360}^ \circ }} \over {{{60}^ \circ }}} - 1 = 5$$
