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

Quantrex Academy · Accepted Answer

Correct answer: B. x ( -1)

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