Question #86c86

Answer 1

a) Low power magnification of this microscope is 60x
b) High power magnification of this microscope is 200x

Explanation:

For calculating magnification of a microscope, two things are needed. First, is the magnification of eyepiece/ocular and second, the magnification of objective. THen, we can use the formula given below to calculate the magnification

Microscope magnification = Ocular lens magnification × Objective lens magnification

Using the formula we can calculate both low and high magnification of the microscope.

a) Ocular lens magnification =20x
Objective lens magnification =3x
Microscope magnification = 20 x 3 = 60x

b) Ocular lens magnification =20x
Objective lens magnification =10x
Microscope magnification = 20 x 10 = 200x
