why does a light ray passing through the optical centre do not suffers refraction?
Asked by kshitij.kulkarni | 18th Jul, 2009, 06:21: PM
If the lens is thin and the radii of curvature of the two refracting surfaces are equal, a ray of ligth passing through its optical centre passes undeviated but for the rays os light passing through the optical centre of a thick lens, the incident and the emergent rays are parallel, but there is a lateral displacement between them.
