Question

An observer observes a person writing something with his right hand. Later he discovered that whatever he saw was the image of the person in a plane mirror. Choose the correct statement.

• A. The person was actually writing with his left hand.
• B. The person was actually writing with his right hand.
• C. Actual writing hand depends on the orientation of the mirror.
• D. Actual writing hand depends on the position of the observer.

Answer 1

The correct option is A The person was actually writing with his left hand.

Image formed in a plane mirror is laterally inverted, i.e. apparent reversal of image along left and right is present. So, if in the image the person appears to be using his right hand for writing then actually he must be writing with his left hand. Moreover, this apparent inversion does not depend on either orientation of the mirror or the position of the observer.
