Question

When a plane mirror is rotated through an angle $\theta$, the reflected ray turns through the angle $2\theta$, then size of the image:

• A. Is doubled
• B. Is halved
• C. Remains the same
• D. Becomes infinite

The correct option is C Remains the same

When a plane mirror is rotated through an angle $\theta$, the reflected ray turns through the angle $2\theta$. But the size of the image remains unaffected only position changes.
