Question 1

What is the purpose of a compound magnification system?

Answer 1

Further enlarges the sample through magnifying the magnification

Question 2

What is an isotropic material?

Answer 2

A material that has the same optical properties in all directions

Question 3

What is an anisotropic material

Answer 3

A material where the optical properties vary with orientation of the incoming light. Most solids

Question 4

What is the purpose of polarized light microscopy?

Answer 4

Causes divided light rays to interact to convert unpolarized light to polarized light. Provides information on absorption colour and optical path boundaries

Question 5

What is birefringence?

Answer 5

The division of light into ordinary and extraordinary rays

Question 6

What is the difference between phosphorescence and fluorescence?

Answer 6
