Question

Name the part of a lens through which a ray of light passes without suffering any deviation

Answer 1

The part of a lens through which a Ray of light passes without suffering any deviation is the OPTICAL CENTRE.

Let's learn a few facts about Optical Centre:

• It is the geometric centre of the lens for bi-concave and bi-convex lens.

• The optical centre of a lens may shift depending upon the shape of the lens.

• The optical centre of the lens is similar to the pole of a spherical mirror.

• In the diagram , "C" represents the optical centre.

• Simply speaking, this type of ray diagram can only be drawn only if the lens is considered to be significantly thin.

• If the lens has thickness, then the ray undergoes deviation at the first and the second surface of the lens but the net outcome comes as zero division.
