Chapter 33: Problem 65

What is the magnification of a telescope with \(f_{0}=1.00 \cdot 10^{2} \mathrm{~cm}\) and \(f_{e}=5.00 \mathrm{~cm} ?\)

Short Answer

Expert verified
Answer: The magnification of the telescope is 20.

Step by step solution

01

Identify the Formula

To find the magnification of the telescope, we have to use the magnification formula: magnification = f0 / fe
02

Plug in Given Values

We're given f0 = 1.00 * 10^2 cm and fe = 5.00 cm. So, we can plug these values into the formula: magnification = (1.00 * 10^2 cm) / (5.00 cm)
03

Calculate the Magnification

Now, we just have to perform the division operation: magnification = (1.00 * 10^2 cm) / (5.00 cm) = 20 So, the magnification of the telescope is 20.

Where is the object located? a) \(6 \mathrm{~cm}\) from the lens on the same side of the lens b) \(6 \mathrm{~cm}\) from the lens on the other side of the lens c) \(96 \mathrm{~cm}\) from the lens on the same side of the lens d) \(96 \mathrm{~cm}\) from the lens on the other side of the lens e) No object could have formed this image.

A classmate claims that by using a \(40.0-\mathrm{cm}\) focal length mirror, he can project onto a screen a \(10.0-\mathrm{cm}\) tall bird locat ed 100 . \(\mathrm{m}\) away. He claims that the image will be no less than \(1.00 \mathrm{~cm}\) tall and inverted. Will he make good on his claim?
