Question

An object placed $3m$ from a plane mirror is shifted further by $0.4m$ away from the mirror. What is the new distance between the object and its image?

• A. $\text{3.8 m}$
• B. $\text{6.6 m}$
• C. $\text{3.4 m}$
• D. $\text{6.8 m}$

Answer 1

The correct option is D $\text{6.8 m}$

After shifting the object by $0.4m$,Object distance from the mirror $=(3+0.4)=3.4m=$ Image distance

Distance between the object and its image $=(3.4+3.4)m=6.8m$
