Question
A concave mirror is placed on a horizontal table with its axis directed vertically upwards. Let O be the pole of the mirror and C its centre of curvature. A point objected is placed at C. It has a real image, also located C. If the mirror is now filled with water, the image will be
Options
A.real and will remain at C
B.real and located at a point between C and ∞
C.virtual and located at a point between C and O
D.real and located at a point between C and O
Solution
The ray diafram is shown in the figure. Therefore, the image will be real and between C and O.
