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.
