A microscope is focused on a mark on a piece of paper and then a slab of glass of thickness 3cm and refractive index 1.5 is placed over the mark. How should the microscope be moved to get the mark in focus again.

Answer:

Hi Vishesh Gupta,

We know that Refractive index = begin mathsize 14px style fraction numerator Real space depth space over denominator space apparent space depth space end fraction end style

apparent depth = begin mathsize 14px style fraction numerator 3 over denominator 1.5 end fraction end style = 2 cm 


So due to refraction the image gets shifted upwards by 1 cm. 

Thus, the microscope has to be moved up by 1 cm to get the mark in focus again
