A Cassegrain telescope is a reflectingtelescope that uses two mirrors, the secondarymirror focusing the image through a hole in theprimary mirror (similar to that shown in thefigure (Figure 1)). You wish to focus the imageof a distant galaxy onto the detector shown inthe figure. If the primary mirror has a focallength of 2.5 m, the secondary mirror has afocal length of -1.5 m and the distance from thevertex of the primary mirror to the detector is 15cm.Figure 1of 1SecondaryPrimaryDetectorPart AWhat should be the distance between thevertices of the two mirrors?Express your answer using twosignificant figures.VOΑΣΦSubmitہےnext>?Provide FeedbackMy Answers Give UpmContinue

A sharp image of a pencil that’s 25 cm away from your eye is formed on your retina. As you move the pencil farther away from your eye, what happens to the lens of your eye in order to form a sharp image on the retina? It gets less curved, increasing its focal length It gets less curved, decreasing its focal length It does not change It gets more curved, increasing its focal length It gets more curved, decreasing its focal length
A physicist places two plane mirrors at an angle of ?1 = 55.5° to each other, as shown below. She then directs a horizontal laser beam toward Mirror 1. The beam reflects twice: first off Mirror 1, then Mirror 2. What angle ?2 will the outgoing beam make with the surface of Mirror 2? (Enter your answer in in degrees.)
A 2.1-cm-tall object is 30 cm to the left of a lens with a focal length of 15 cm. A second lens with a focal length of -5 cm is 45 cm to the right of the first lens. Calculate the distance between the first image and the second lens. Calculate the image height.

Famous jeweler Gabi Tolkowsky is looking at a 3.0-cm-tall perfect oval-shaped diamond through a thin lens. The diamond is 20.0 cm behind the lens, and the distance between its upright image and the lens is 40.0 cm. What is the focal length of the lens? Is it converging or diverging? How tall is the image?   PLEASE PLEASE draw a ray diagram and define variables
You are having trouble reading your cheat sheet during your physics exam because you wrote so small. You foresaw the problem, so you brought a small lens with you to the exam. You hold the lens 6 cm away from the page. The image you see is upright and 2.9 times the size of the writing on the page. where is image formed Is the image real or virtual what is the focal length of the lens are you using a converting lens or a diverging lens
A diverging lens has a focal distance of f=0.2 cm. If an object is placed 0.1cm away, What is the image distance? Is the image real or virtual? What is the magnification?
A 3.0 cm tall object is positioned 15.5 cm from a converging lens. The focal length of the lens is 10.5 cm. What is the distance to the image? What is the magnification of the image? What is the height of the image? Is the image real or virtual? Is the image inverted or upright?
Determine the distance from the second lens to the final image.
