Question

Four properties of image formed of concve mirror

Answer 1

CONCAVE MIRRORS;

1. They always produce real and inverted images except when an object is placed between the mirror pole and the focus which gives erect virtual images. (for real objects)

2. They produce magnified, diminished and same size images.

3.A parallel beam of incident light is concentrated on its focus and thus such a mirror is called a convergent mirror. Also a light source placed at the focus produces a parallel light beam.

4.Sign convention: The focal length and radius of curvature are taken as negative.

Hope this helps
