Calculate linear magnification of images and answer to
following questions.
1. What is the actual size of bacteria?
2nm
3μm

Answer 1

Ответ:

The linear magnification of an image can be calculated using the following formula:

Linear Magnification (M) = Image Size / Object Size

Where:

Linear Magnification (M) is the magnification factor.

Image Size is the size of the image produced by the microscope.

Object Size is the actual size of the object (in this case, bacteria).

Let's calculate the linear magnification for both cases:

For bacteria with an actual size of 2 nanometers (2 nm):

M = Image Size / Object Size

M = 3 μm / 2 nm

First, we need to convert 3 μm to nanometers (nm):

3 μm = 3,000 nm

Now, we can calculate M:

M = 3,000 nm / 2 nm

M = 1,500

So, the linear magnification for bacteria with an actual size of 2 nm is 1,500.

For bacteria with an actual size of 3 micrometers (3 μm):

M = Image Size / Object Size

M = 3 μm / 3 μm

Since the object size and image size are the same in this case (both 3 μm), the linear magnification is 1.

Answers to your questions:

The actual size of bacteria is 2 nanometers (2 nm).

The actual size of bacteria is 3 micrometers (3 μm).
