Question

Experiment setup for determine refractive index of water using concave mirror

Answer 1

Answer:

The experiment From (1), the focal length of the concave mirror is f = FV = R/2.

When the mirror is filled with water, the apparent centre of curvature C' moves down, and the apparent radius of curvature becomes R' = C'V. The new focal length is given by f' = F'V = R'/2.

Answer 2

Heya Mate.....

Schematics of the spherical concave mirror experiment for measuring therefractive index of water. The support holding the lamp is moved up and down until a sharp image of the lamp is formed on the screen. Formation of the images at the positions of the actual and apparent centres of curvature.

Hope this will help you....
