MICROSCOPY

Is there a change in the level of brightness of the field of view when the objective is shifted from LPO to HPO?

What portion of letter e is magnified under HPO?

Is there an increase or a decrease in the area of the specimen seen?

MICROSCOPY

Is the orientation of the letter “e” changed by shifting from LPO to HPO?

If the tail end of the letter “e” is to be viewed under the HPO, where should it (the tail end) be positioned under LPO before shifting into HPO?

To ensure easier focusing, what should be done first before the HPO is swung into position?

MICROSCOPY

When may the coarse adjustment knob be used?

When is the coarse adjustment knob not used?

Compute the theoretical magnification of the letter “e” under LPO and the HPO.

When one thread is in focus, are the other threads in focus too?

MICROSCOPY

What is the color sequence of the threads from bottom to top?

When one thread is in focus, are the other threads in focus too?

In which objective is it easier to determine the sequence of the colored threads? Why?
