A glass slab of thickness and refractive index is placed over a photo. The apparent shift in position of the photo is ____ cm.
Step 1: Given data
The thickness of the glass slab
Refractive index of glass slab
Let the Apparent Shift be A.
Step 2: Calculating apparent shift
The apparent shift is given by:
Thus, the apparent shift of the photo is .
Hence, option (B) is the correct answer.
