An ink mark is made on a piece of paper on which a glass slab of thickness ' t ' is placed. The ink mark appears to be raised up through a distance ' x ' when viewed at nearly normal incidence. If the refractive index of the material of glass slab is ' ' then the thickness of glass slab is given by

Quantrex Academy · Accepted Answer

Correct answer: A. x -1

Here, the normal shift is x The formula for the normal shift is aligned x & =t (1- 1 ) t & = x (1- 1 ) x & =t (1- 1 ) t & = x (1- 1 ) t & = x ( -1) aligned
