Microscope help! 1. which part of the microscope provides concentration of light coming out of a light source?
a. oculars
b. objective
c. condenser
d. light bulbs on/off switch
e. none of the above

2. what is the total magnification of the cells when using the immersion objective of bright field microscope?
a. 40
b. 10
c. 100
d. 400
e. none of the above

3. the role of the immersion oil is to___
a. prevent the loss of light by refraction
b. make objective gentle touching a slide
c. magnify 1000x
d. concentrate light coming from the bulb
e. none of the above

1. Condenser

2. None of the above

3. Magnify 1000x

Explanation:

1. Illuminators provides the stable light source in the microscope. It can be reflected using a mirror for a built in microscope. Condenser is made up of two lenses which helps collect and concentrate light. The light beams passes through the centre of the lenses.

Total magnification is objective magnification × Ocular magnification

It makes the object appear bigger than it is. Any of the objective magnification can be uses to achieve the specific size. Objective ranges from 10-100

Oil immersion makes image appears brighter, they increase the refractive index. It is used with 100x objects to achieve a clearer image.

protist eukaryotes that are not plants, animals, or fungi ("misfits")

the answer is trees if i'm not mistaken
