Question

a candle is kept in front of a plane mirror at distance 15 cm what is the distance between the candle and its image​

Answer 1

As we know that, the image formed by a plane mirror is at the same distance behind the mirror as the object is in front of the mirror.

Therefore, the image is also formed at 15 cm behind the mirror.

Thus, Distance between the candle and its image = 15 + 15 = 30 cm
