Question

(c)Nabeel is observing his image in plane mirror. The distance between the mirror and his image is Sm. If he moves 2 m the mirror then what will be the distance between Nabeel and his image? (Solve using step)
​

Answer 1

Answer:

in the case of a plane mirror, the distance between the object and the mirror (d1) is same as the distance between image and mirror (d2).

Distance between the mirror and David’s image, d2 = 4 m

Therefore, d1 = d2 = 4 m

If David moves 1 m towards the mirror, then d1 = 4 − 1 = 3m Again, d1 = d2 = 3 m Therefore, the distance between David and his image is d1 + d2 = 3 + 3 = 6 m
