Answer:
The distance of the candle from the plane mirror is 15 centimetres.
The distance between the candle and it's image.
Explanation:
Solution,
In case of the image formed by a plane mirror,
The distance between object and mirror surface. = The distance between mirror surface and the image.
So,
Distance between object and it's image = 2× The distance between object and mirror.
By applying the above formula,we get that,
Distance between candle and it's image
= 15×2 = 30 centimetres
