Question
A concave mirror of radius 40 cm lies an a horizontal table and water is filled in it up to a height of 5.0 a. A small dust particle P floats on the surface of the water. Particle P lies vertically above the point of contact of the minor with the table. Locate the image of the dust particle as seen from a point directly above it. The refractive index of water is 4/3.
- 2.75 cm below water surface
- 8.75 cm below water surface
- 5.75 cm above water surface
- 6.75 m above water surface
The correct answer is: 5.75 cm above water surface
