Question
As shown in the figure a particle is placed at O in front a plane mirror M.A man at P can move along path PY and PY’ then which of the following is true ?
Options
A.For All points on PY man can see the image of O
B.For All points on PY’ man can see the image but for no point on PY he can see the image of O
C.For al; points on PY’ he can see the image but on PY he can see the image only up to distance d.
D.He can see the image only up to a distance d on either side of P.
Solution
Field of view of image is decided by the reflected rays.As we can see that the reflected rays from the extreme end points of mirror at a height ‘d’ from P and below P all points on Py’, Hence (C)
