Microscope Basics Quiz

What is the primary function of a microscope in biology?

• To change the color of specimens

• To make large objects appear smaller

• To measure the weight of specimens

• To magnify small specimens for detailed study

Where should your eye be positioned when using the ocular lens?

• Closed while using the lens

• Directly touching the lens

• Slightly hovering over the lens

• Far away from the lens

What is the function of the nose piece on a microscope?

• To hold the microscope steady

• To hold and rotate the objective lenses

• To adjust the light intensity

• To connect the ocular lens to the body tube

Which part of the microscope is used to control the amount of light entering through the stage?

• Nose piece

• Diaphragm

• Ocular lens

• Stage clips

What is the purpose of the coarse adjustment knob?

• To rotate the nose piece

• To adjust the light intensity

• To move the stage up and down for a clearer view

• To hold the specimen in place

How do you calculate the total magnification of a specimen?

• Subtract the magnification of the ocular lens from the objective lens

• Multiply the magnifications of the ocular and objective lenses

• Divide the magnification of the objective lens by the ocular lens

• Add the magnifications of the ocular and objective lenses

Which type of lens is used in microscopes to magnify specimens?

• Concave lens

• Convex lens

• Flat lens

• Cylindrical lens

What is the first step in viewing a slide under a microscope?

• Adjust the diaphragm

• Ensure the nose piece is clicked in with the lowest power objective lens facing down

• Use the fine adjustment knob

• Turn on the light source

What is a key difference between prepared slides and wet mount slides?

• Prepared slides are made by companies and do not contain live organisms

• Prepared slides contain live organisms

• Wet mount slides are permanently created

• Wet mount slides do not require a cover slip

Why is it important to reduce air bubbles when making a wet mount slide?

• Air bubbles increase the magnification

• Air bubbles make the slide heavier

• Air bubbles can be mistaken for the specimen

• Air bubbles can damage the microscope
