You've been asked to build a telescope from a magnifying 2.0x lens and a 5.0x magnifying lens....
Homework Answers
Magnification: 1.5x
Dimensions: 5.0" x 2.5" x 1.0"
Weight: 0.65oz / 16 grams
a. What is the maximum magnification you can achieve?
fo/fe [1+fe/D]
b. Which lens should be used as the objective? Explain.
5x
c. What will be the length of your telescope?
length=fo+feD/fe+D=5x+2x*0.25/2x+0.25 where x is themultiplying factor.

A jeweler examines a diamond with a magnifying glass. If the near-point distance of the jeweler is 20.7 cm, and the focal length of the magnifying glass is 7.00 cm, find the angular magnification when the diamond is held at the focal point of the magnifier. Assume the magnifying glass is directly in front of the jeweler's eyes. (Include the sign.) ✕ A grade-school student plans to build a 55 power telescope as a science fair project. She starts with...

You want to build a Galilean Telescope. Your Objective lens is convex with a focal point at 35cm. The Eyepiece is 12.5cm concave lens. Draw a diagram of the placement of the lenses showing their focal lengths in the diagrams showing the distance between the 2 lenses. Calculate the magnification of the device, show all steps.

11. You've been asked to build a machine for a TV commercial that launches soda bottles from ground level over a volleyball net. You estimate the soda needs to clear at least 8 feet in order to sail over the net. The equation that represents the height of the bottle as a function of time (t) in seconds is: h= -16t2 + 30.4t How many times does the soda cross the 8 foot threshold? O 2 O 1 Oo

1) What is the total magnification of a refracting telescope having an objective and eyepiece lens of focal lengths 30.0 cm and 0.40 cm respectively? 2) If the focal lengths of both the objective lens and the eyepiece were doubled in a compound microscope, what would be the change in the magnification? 3) If you wish to look at Mars or any planet with a telescope, what sort of objective lens and eyepiece lens should you use? A. Objective long...
