Question

Give the properties of image formed by a plane mirror

Answer 1

The properties of the image formed by a plane mirror

The image is upright ( erect ) , The image is equal to the the object in the size , The image is laterally inverted ( reversed ) and the image can not be received on a screen as it is virtual  .

The distance between the object and the mirror is equal to the distance between the image and the mirror , The straight line joining the object to its image is perpendicular to the surface of the mirror.

Answer 2

Answer:

✮ Properties of Image Formed By a Plane Mirror:

• The image formed by a plane mirror is virtual, erect and laterally inverted.

• Image and object are equidistance from the mirror.

• The image is of the same size as object.

• When the plane mirror is rotated through a certain angle, the reflected ray turns through double the angle.

• The minimum height of the mirror to be required to see the full image of an object of height h is h/2.

✮ Example:

• An object is placed between two plane mirrors inclined to each other at an angle of 60°.

Here,

θ = 60°

n = 360°/θ - 1

= 360°/60 - 1

= 6 - 1

= 5
