Answer 2

False

Question 3

Micro spectrophotometry combines a compound microscope and a spectrophotometer.

Answer 3

True

Question 4

An electron microscope is more powerful than a polarized light microscope.

Question 5

A simple convex lens is the most complex type of lens.

Question 6

Microscopes primarily work by refracting light rays as they pass through the lens of the microscope.

Question 7

A microscope made from one convex lens is known as a compound microscope.

Question 8

The resolution of a lenses is described by its numerical aperture.

Question 9

An attempt to increase magnification of an object 1000 times the numerical aperture of the objective lens is known as maximum magnification.

B) bifocal
C) trifocal
D) parfocal
