An object is placed at a distance of in front of a plane mirror. The virtual and erect image is formed by the mirror. Now the mirror is moved by towards the stationary object. The distance by which the position of image would be shifted, will be
Options
- A towards mirror
- B towards mirror
- C away from mirror
- D towards mirror
Correct answer
B. towards mirror
Step-by-step solution
When an object is placed in front of a plane mirror, object distance is equal to the image distance. In the first case, the image distance will be from the mirror. In the next case, as the mirror is moved towards the object, the object distance becomes . Hence, image distance will also be .
