Question

the working distance decrease as magnification increases?
true
false
question 23
when using the microscope, the initial setting should always begin with the low power scanning objective in place and the stage raised.
true
false
question 24
the ocular changes the distance between the slide and the objective to focus an image.
true
false
question 25
the magnification of the objective is 10x is known as:
high power
medium power

Explanation:

• For Question 22: In microscopy, as magnification increases, the working distance (distance between the objective lens and the specimen) decreases.
• For Question 23: When using a microscope, it is standard practice to start with the low - power scanning objective to get an overview and then move to higher powers.
• For Question 24: The ocular (eyepiece) does not change the distance between the slide and the objective. The focusing mechanisms like the coarse and fine adjustment knobs are used for that.
• For Question 25: An objective with 10x magnification is considered medium - power. A 4x objective is low - power and 40x or higher is high - power.

Answer:

Question 22: A. True
Question 23: A. True
Question 24: B. False
Question 25: B. medium power
