Question

​

Answer 1

Answer:

(i) Plane mirror forms an erect image.

(ii) It forms a virtual image.

(iii) Size of the image is same as that of the object.

(iv) Image is formed at the same distance behind the mirror as the object stands in front of it.

(v)Image formed is a laterally inverted image i.e., right hand side of the object seems to be the left hand side and vice-versa.

Answer 2

Answer:

first law of reflection : the incident ray the normal drawn at the point of of incidence and the reflected ray all lie in a same plane.

second law of reflection: a Ray of a light is reflected by a surface the angle of incidence is equal to the angle of reflection.

characteristics of the image formed by a plane mirror:

• the image is upright and virtual the image is formed as far as the object is in front of it
• the image is upright and virtual the image is formed as far as the object is in front of itthe image is of same size as the object
• the image is upright and virtual the image is formed as far as the object is in front of itthe image is of same size as the objectthe image is laterally inverted
