Write four properties of concave and convex mirror

1.	Write four properties of concave and convex mirror
Answer» Properties of the image formed by a convex mirror :1) The image is always virtual and erect.2) The image is highly diminished or point sized.3) It is always formed between F and P.4) The object and image are on opposite sides of mirror.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.
