bharath stands in front of of plane mirror at a distance of 5cm. from the mirror and observes his image in mirror. if he moves 2cm. towards the plane mirror ,then what will be the distance between bharath and his image?
Answers
Distance from bharat and mirror is 5-2=3cm.
Image and mirror is also 3cm(only in case of plane mirror.)
So distance between bharath and image is 3+3=6
Concept:
The image distance and object distance are always equal for a plane mirror.
Given:
Distance of Bharath from plane mirror = 5cm
Find:
We need to determine the distance between Bharath and his image when he moves 2cm towards the plane mirror.
Solution:
A plane mirror is a mirror with a flat reflective surface. The angle of reflection for light rays striking a planar mirror is the same as the angle of incidence.
Here, 5 is the distance of Bharath from the plane mirror and 2 is the distance when he moves toward the plane mirror.
Therefore, Bharat and the mirror are separated by a distance of 5-2=3 cm.
The image distance and object distance are always equal for a plane mirror.
Each mirror and image measures 3 cm (only in the case of the plane mirror.)
Bharath and the image are therefore separated by 3+3=6cm.
Thus, the distance between Bharath and his image is 6cm.
