Question

A ball is held 50 cm in front of a plane mirror the distance between the ball and its images is

Answer 1

100cm the distance between the ball and it's image because the image of the ball will be 50 cm inside the mirror

Answer 2

Distance between image and the ball is 100cm.

Explanation:

• Plane mirror is a flat reflecting surface.
• When an object is placed in-front of a plane mirror, a virtual image is formed which is behind the mirror.
• The virtual image which is formed is erect in nature and is laterally inverted.
• The distance of image from plane mirror is the same as the distance of object from the mirror.
• Here, the object is a ball which is kept at a distance of 50 cm in-front of the mirror.
• So, the distance of the image is also at 50 cm behind the mirror.
• And therefore, distance between image and the object is 100cm.
