Question

If you hold a pen in your right hand and stand in front of the mirror, the pen will be in the left hand in the image. This phenomenon is called
(a) lateral inversion
(b) diffraction
(c) reflection
(d) inversion

Answer 1

Answer:

The phenomenon in which the right hand side of the object appears to be the left hand side of the image is called lateral inversion. Hence, option (a) is correct.

Answer 2

Answer:

The pen which is in the right hand appears to be in the left hand due to the phenomenon called lateral inversion. Option (a) is correct.

Explanation:

• When the waves get spread around the obstacles, the phenomenon is called diffraction.
• When an object's image appears to be inverted, the phenomenon is called inversion.
• When a polished surface bounces rays of light falling on it, the process is called reflection.

Lateral inversion is the phenomenon in which the right side of the object appears to be on the left side and vice versa behind the plane mirror.

So, the pen which is in the right hand appears to be in the left hand in the image due to the phenomenon called lateral inversion.

Option (a) is correct.
