Question

To find the value of v for different values of u readings incase of a concave mirror and to find the focal lenghtg

Answer 1

Answer:

see explanation

Explanation:

Draw AB and AD perpendicular on x' and y'- axis. For point A, the values of u and v will be the same. The coordinates at A is (2f, 2f) as u and v are same for a concave mirror when the object is placed at the centre of curvature. Hence, u = v = R = 2f.

Answer 2

Draw AB and AD perpendicular on x' and y'- axis. For point A, the values of u and v will be the same. The coordinates at A is (2f, 2f) as u and v are same for a concave mirror when the object is placed at the centre of curvature. Hence, u = v = R = 2f.
