Why a ray of light do not deviate its path when it passes from optical centre

Posted by Tanishq Tandon 5 years, 10 months ago

CBSE > Class 10 > Science

1 answers

Meghna Thapar 5 years, 10 months ago

Deviation is the change in direction of the ray while passing through the lens. The middle portion of the lens is comparatively flat and there is a point on the principal axis and inside the sphere through which all the undeviated rays pass. When we say that there is no deviation, we only mean that the incident ray and the emergent ray are parallel to each other. For thin lenses, the refraction inside the lens is negligible and therefore we represent the ray passing through the optic centre as a straight line.
