Question

A microscope is focused on an ink dot on a white paper. A glass slab of thickness $0.03 m$ with $μ = 1.5$ is placed on the paper. To focus the ink dot clearly the microscope must be:

Solution

The correct option is B Raised by $0.01 m$
Shift in the object
$= (1 - \frac{1}{μ}) Δ t = (1 - \frac{1}{1.5}) \times 0.03 m$
$= 0.01 m$
So,to focus the ink drop, the microscope must be raised by 0.01m. as we are in rarer medium the image appears raised. so, the microscope needs to be raised 0.01m to focus clearly.
