Problem

Let's have a point source of light and a planar glass panel with a refractive index

n = 1.50

. In the foot of the perpendicular from the source to the panel there are wavefronts with a radius of curvature

R = 5.00\,\mathrm{m}

inside the glass. What is the real distance between the source and the panel?
