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 object is placed at C. It has a real image, also located at C. If the mirror is now filled with water, the image will be.

A

real and will remain at C

B

real and located at a point between C and `oo`

C

virtual and located at a point between C and O

D

real and located at a point between C and O

Text Solution

Verified by Experts
