Two rays traveling parallel to the principal axis strike a large plano-convex lens having a refractive index of 1.50 (see figure below). If the convex face is spherical, a ray near the edge does not pass through the focal point (spherical aberration occurs). Assume this face has a radius of curvature of R = 21.2 cm and the two rays are at distances h, = 0.500 cm and h, = 11.9 cm from the principal axis. Find the difference Ax...

A plano-convex lens is immersed in a liquid that has a refractive index n1. Derive the lens maker’s equation (shown below) in this situation assuming that n1 is smaller than the refractive index of the lens (nL). Lens maker equation: 1/f = (n1-1)/r where f: focal length of lens and r: radius of curvature of lens
