Amicroscope is focused on an amoeba. part a when a 0.15-mm-thick cover glass (n=1.50) is placed over the amoeba, by how far must the microscope objective be moved to bring the organism back into focus? express your answer in millimeters. δsδ s = nothing mm request answer part b must it be raised or lowered?

∵The apparent depth is less therefore we need to raise the objective away from the placed object.

Explanation:

Given:

Real depth,

refractive index of the medium,

We know,

where:

apparent depth of the object

Now, the difference in the real and apparent depths:

∵The apparent depth is less therefore we need to raise the objective away from the placed object.
