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 it's centre of curvature. A point object is placed at C. It has a real image, also located at C (a condition called auto-collimation). If the mirror is now filled with water, the image will be:
Options:
Answer:
D
Solution:
Due to refraction at water surface object will appear beyond C. This image will act as an object for reflection by mirror. So image will be real, and located between C and O
