Calculating Microscope Magnification

a.) What is the low power magnification of a microscope with a 20x ocular and a 10x objective?

Calculate the low power magnification.

b.) What is the high power magnification of a microscope with a 20x ocular and a 43x objective?

Calculate the high power magnification.

Answer:

Lower power magnification: 20 x 10 = 200x

Higher power magnification: 20 x 43 = 860x

Microscopes are essential tools in the field of science, allowing us to explore and discover the micro world around us. Understanding how to calculate the magnification of a microscope is crucial for accurate observations and analysis.

Low Power Magnification Calculation:

When using the 20x ocular (eyepiece) and the 10x objective, the formula to calculate the total magnification is:

Low power magnification = Ocular magnification x Objective magnification

Substitute the values: 20 x 10 = 200x. Therefore, the low power magnification of this microscope is 200x.

High Power Magnification Calculation:

For the high power magnification using the 20x ocular and the 43x objective, apply the same formula:

High power magnification = Ocular magnification x Objective magnification

By substituting the values: 20 x 43 = 860x. Hence, the high power magnification of this microscope is 860x.
