Chapter 35: Q. 41 (page 1018)

White light is incident onto a 30掳prism at the 40掳angleshown in Figure p35.41. Violet light emerges perpendicular to the rear face of the prism. The index of refraction of violet light in this glass is 20%larger than the index of refraction of red light. At what angle蠒does red light emerges from the rear face?

The Hubble Space Telescope has a mirror diameter of 2.4 m. Suppose the telescope is used to photograph stars near the center of our galaxy, 30,000 light years away, using red light with a wavelength of 650 nm.

a. What鈥檚 the distance (in km) between two stars that are marginally resolved? The resolution of a reflecting telescope is calculated exactly the same as for a refracting telescope.

b. For comparison, what is this distance as a multiple of the distance of Jupiter from the sun?

Infrared telescope, which use special infrared dictators, are able to do peer farther into star-forming regions of the galaxy because infrared light is not scattered as strongly as is visible light by the tenuous clouds of hydrogen gas from which new stars are created. for what wavelength of light is the scattering only 1%that of light with visible wavelength of 500nm?

A 2.0cm-tall object is 20cmto the left of a lens with a focal length of10cm. A second lens with a focal length of5cmis 30cmto the right of the first lens.

a. Use ray tracing to find the position and height of the image. Do this accurately using a ruler or paper with a grid, then make measurements on your diagram.

b. Calculate the image position and height. Compare with your ray-tracing answers in part a.

High-power lasers are used to cut and weld materials by focusing the laser beam to a very small spot. This is like using a magnifying lens to focus the sun light to a small spot that can burn things. As an engineer you have designed a laser cutting device in which the material to be cut is placed 5.0cmbehind the lens. you have selected a high-power laser with a wavelength of

your calculation indicates that the laser must be focused to a 5.0-渭m-diameterspot in order to have sufficient power to make the cut. what is the minimum diameter of lens you must install?

A microscope with a tube length of 180 mm achieves a total magnification of 800* with a 40* objective and a 20* eyepiece. The microscope is focused for viewing with a relaxed eye. How far is the sample from the objective lens?
