Question

The distance between the object and the image formed by a plane mirror is 30 cm. What is the distance between the image and plane mirror?

• A. 10 cm
• B. 30 cm
• C. 15 cm
• D. 20 cm

Answer 1

The correct option is C 15 cm

We know,
Object distance = Image distance

As per the question,
Object distance + Image distance $=30cm$

From this,
distance between the image and plane mirror $=\frac{30}{2}=15cm$
