Question

Activity 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).

Answer 2

To calculate the linear magnification of an image, you need two pieces of information: the actual size of the object and the size of the object in the image. In this case, you've provided the actual size of bacteria, which is 2 nanometers (2 nm).

Let's assume you have an image of bacteria, and you want to find the linear magnification. If the size of the bacteria in the image is given as 3 micrometers (3 μm), you can use the following formula to calculate the linear magnification (M):

M = Image size / Actual size

M = (3 μm) / (2 nm)

First, we need to ensure that both the image size and actual size are in the same units. Since 1 μm (micrometer) is equal to 1000 nm (nanometers), we can convert the image size to nanometers:

M = (3000 nm) / (2 nm)

Now, you can calculate the linear magnification:

M = 1500

So, the linear magnification of the image is 1500 times. This means that the bacteria in the image appears 1500 times larger than its actual size.

To answer your questions:

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

2. The size of the bacteria in the image is 3 micrometers (3 μm), and the linear magnification of the image is 1500 times.
