A printed page is kept pressed to a glass cube `(mu=1.5)` of edge 6.0 cm. By what amount will the printed letters appear to the shifted when viewed from the top?

Text Solution

Verified by Experts

The thickness of the cube =t=6.0. The shift in the position of the printed letters is
`/_\t=(1-1/mu)t`
`=(1-1/1.5)xx6.0cm=2.0cm`
