Question

question 27: the changing of the distance between the slide and the objective to focus on an image: ocular iris diaphragm illuminator course adjustment question 28: if the magnification of the objective is 10x and the magnification of the ocular is 10x, what is the total magnification: 40 1000 100 10

Explanation:

• Question 27: The course adjustment knob on a microscope changes the distance between the slide and the objective to focus on an image. The ocular is the eyepiece, the iris diaphragm controls light, and the illuminator provides light.
• Question 28: Total magnification of a microscope is calculated by multiplying the magnification of the objective lens by the magnification of the ocular lens. So, if objective is 10x and ocular is 10x, 10×10 = 100.

Answer:

Question 27: course adjustment
Question 28: 100
