Question

Important 5 points of plane mirror.

Answer 1

hello friend
here is the answer of ur question

A plane mirror is a mirror with a flat  reflective surface.

A straight line drawn from part of an object to the corresponding part of its image makes a right angle with, and is bisected by, the surface of the plane mirror. 

The image formed by a plane mirror is always virtual , upright, and of the same shape and size as the object it is reflecting.

Plane mirrors are the only type of mirror for which a real object always produces an image that is virtual, erect and of the same size as the object.
Virtual objects produce real images, however. The focal length of a plane mirror is infinite; its optical power is zero.

The angle of incidence is the angle between the incident ray and the surface normal.

hope this helps!!

Answer 2

1... focal length infinity

2. Image will be same size but virtual

3. If angle of incident make angle Ø then reflected ray also amke angle Ø

4. It makes left area image in right side

5. The surface of mirror is flat
