Question

An object is kept at 60cm in front of plane mirror .If the mirror is now moved 25 cm away from the object , how does image shift from its previous position?

Answer 1

Answer:

50cm

Explanation:

Distance of the object from the mirror = 60 cm. Therefore, image is formed at a distance 60 cm from the mirror, behind it. Thus, the image shifts 50 cm away.

Answer 2

Answer:

Here is your answer

Suppose a plane mirror is kept at 60cm in front of an object. Now the position of the image made by the mirror is (60x2)= 120cm (inside the mirror) from the object. As shown is the figure, If we move the mirror 25cm from the object then it will make the distance of mirror-object 60+25=85cm

So the new image of the object will be created at (85x2)=170cm away from the object.

Now we can say that the image will shift (170-120)= 50cm away from the previous position (As shown in the picture)
