If an image is blurry under a microscope, how do you make it clearer?

• Change the objective lens to a higher magnification.

• Turn on the light or adjust the mirror.

• Turn the focusing wheel until the image is focused.

• Use a different eyepiece lens.

What is the equation to work out overall magnification from eyepiece magnification and objective lens magnification?

• Overall= Objective x Eyepiece

• Overall= Objective/Eyepiece

• Overall= Eyepiece/Objective

How do you calculate actual specimen size from magnification and image size?

• Actual = Magnification / Image Size

• Actual =Image Size / Magnification

• Actual = Image Size x Magnification

• A cell with a nucleus

• A cell without a cell membrane

• A cell with two nuclei.
