Assume that a certain spherical mirror has a focal length of -10.0 cm. Locate and describe the
image for object distances of (a) 25.0 cm (b) 10.0 cm (c) 5.0 cm.

Text Solution

Verified by Experts

The correct Answer is:

A, B, C

Apply `1/v+1/u=1/f`
(a) `f=-10cm, u=-25cm`
Solving ,we get `v=-16.7 cm`
Since, v is negative , image is in front of mirror .So, it is real, Similarly, we can solve for other parts.
