Question

When a plane mirror is rotated through an angle 5° keeping the position of the source constant, then its refelcted ray rotates through an angle​

Answer 1

Answer:

When a plane mirror is rotated at an angle θ, the reflected ray rotates through the angle 2θ. However, the size of the image remains unchanged only position shifts. So, the correct answer is “Option C”. Note: For a fixed incident beam, the reflection angle is double the angle through which the reflector has rotated.
