Question

6. BIOLOGY Mr. Fletcher is looking at a 0.5 millimeter section of plant under a microscope. The plant section appears enlarged by a scale factor of 10 when looking through the microscope. He uses the camera on the microscope to photograph what is seen through the lenses at a scale factor of 20 . What is the length of the section of plant in the photograph?

Answer 1

100 millimeters.

Explanation:

Original Length of the plant section = 0.5 millimeter

The microscope enlarges the plant section by a scale factor of 10.

`\text{Length}=0.5*10\; =5\; mm`

Next, the photograph enlarges the microscope image by a scale factor of 20.

`\text{Length in the photograph}=5*20\; mm=100\; mm`

Therefore, the length of the section of the plant in the photograph is 100 millimeters.
