Explain why images seen through flat, smooth, uniform, plate-glass windows are undistorted.arrow_forward(Problem 5.7 of Textbook): What size telescope (diameter of aperture) is required to resolve the components of a double star whose linear separation is 100 million km and whose distance from the earth is 10 light years? (Take 1 500 nm and one light year equals 9.5 trillion km). What is the minimum focal length of objective lens (fo) of the telescope so that human eyes can resolve the components of this double star using this telescope? (Assume that aperture diameter of human eye is 4mm and focal length of eyepiece is fe = 2cm).arrow_forwardThe primary optical element of the Hubble Space Telescope (HST) is 3.2 m in diameter and has a focal length of 62 m. (Treat it as a simple, single lens for this homework) The telescope is aimed at Jupiter and the collected light is focused onto a sensitive Charge Coupled Device (CCD) detector, similar to what is in a digital camera. Each pixel in the detector is a 21 μm x 21 μm square, and the full CCD is 4096 x 4096 pixels. Thus the CCD is about one square inch in size. The HST is in orbit very close to the Earth (compared to other distances in the Solar system). Size of Jupiter: 139,820 km in diameter Distance to Jupiter: 778 million km Look up the size of Jupiter and the distance to Jupiter when it is closest to Earth.

- The Thirty Meter Telescope is a new telescope proposed for the top of the volcano Maunakea that is opposed by many native Hawaiians. Its circular mirror will be 30 m in diameter. In December 2028, Mars will be at its closest approach to Earth (this happens every three years). An astronomer has predicted that, when finished, the telescope will be able to resolve objects that are approximately 2.0 km across on Mars assuming perfect viewing conditions. Approximately how far away is Mars from the Earth when this happens? The dominate wavelengths of visible light coming from Mars are in the range of 500 nm to 700 nm.arrow_forwardA small telescope has a concave mirror with a 2.50 m radius of curvature for its objective. Its eyepiece is a 3.80 cm focal length lens. (a) What is the telescope's angular magnification? (b) What angle in degrees is subtended by a 26,500 km diameter sunspot?

Based on what YOU learned about image formation in Chapter 9, describe how you might design a photocopying machine that could make a copy that is enlarged or reduced compared to the size of the original.arrow_forwardPeople are often bothered when they discover that reflecting telescopes have a second mirror in the middle to bring the light out to an accessible focus where big instruments can be mounted. “Don’t you lose light?” people ask. Well, yes, you do, but there is no better alternative. You can estimate how much light is lost by such an arrangement. The primary mirror (the one at the bottom in Figure 6.6) of the Gemini North telescope is 8 m in diameter. The secondary mirror at the top is about 1 m in diameter. Use the formula for the area of a circle to estimate what fraction of the light is blocked by the secondary mirror. Figure 6.6 Focus Arrangements for Reflecting Telescopes. Reflecting telescopes have different options for where the light is brought to a focus. With prime focus, light is detected where it comes to a focus after reflecting from the primary mirror. With Newtonian focus, light is reflected by a small secondary mirror off to one side, where it can be detected (see also Figure 6.5). Most large professional telescopes have a Cassegrain focus in which light is reflected by the secondary mirror down through a hole in the primary mirror to an observing station below the telescope.arrow_forward(Indicates a review question, which means it requires only a basic understanding of the material to answer.

Which of the numbered locations 1 through 5 best represents the location of the image of the source S seen by the observer? Justify your choice by appealing to the appropriate law(s) of optics.arrow_forward
