The student measured the width of 5 different palisade cells at a total magnification of X400

Eyepiece lenses are usually x5 or x10 magnification.

What combination of eyepiece and objective lenses would give a total magnification

of 400?

Eyepiece lens

Objective lens

(1)

Eyepiece lens: 10x

Objective lens: 40x

Total magnification: 400x

Explanation:

In microscopy, magnification is defined as the degree of visual enlargement of the final image observed by the user. This value is measured by multiples, i.e., by comparing the real size of the image and the final virtual image formed by the microscope lenses. For example, a 10x magnification indicates that the virtual image has been enlarged to 10 times its original size. The total magnification can easily be calculated by multiplying the magnification of the objective lens (generally 4x, 10x or 40x) by the magnification of the eyepiece lens, usually 10x.

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
