Microscopes

Question 1

Define magnification.

Answer 1

How much bigger the image is compared with the actual size of the object.

Question 2

Define resolution / resolving power.

Answer 2

• The smallest distance that points can be spereated and still be seen as separate items.
• The amount of detail an image appears in is dependent on the removing power of the microscope.

Question 3

What affects resolving power?

Answer 3

• It is limited by the wavelength of light used by the microscope.
• The shorted the wavelength used to see a specimen, the higher the resolution.

Question 4

What affects resolving power?

Answer 4

• It is limited by the wavelength of light used by the microscope.
• The shorted the wavelength used to see a specimen, the higher the resolution.

Question 5

What do light microscopes use to form an image?

Answer 5

Light

Question 6

What do electron microscopes use to form an image?

Answer 6

Electrons
