Question

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

Answer 1

Initial distance of object (u):

60 cm

Since,

In a plane mirror

Distance of object is equal to Distance of image

u=v

Image distance is also 60 cm

Now,

If object is shifted 25 cm away then image also shifts 25 cm away
