As light travels from air into water, what happens to the frequency of the light? Consider how the wavelength and speed of light change; then use the relationship between speed, wavelength, and frequency for a wave. What about light that is reflected off the surface of water? What happens to its wavelength, speed, and frequency?

Using Figure 9.34, discuss how you would find the angles of refraction for a
light ray passing from air into glass with the following angles of incidence:
5°, 10° and 20°. Do you notice a trend in the resulting values? If so, describe
it. How does your value compare with that inferred from Figure 9.34?

The ray of light from the ray box should be as narrow as possible.Explain why using a wider ray would give less accurate results than using a narrower ray.

- Crystal lattices can be examined with X-rays but not UV. Why?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_forwardPlease answer the following question(s): 1. When light passes from air to water (refractive index 1.33), its wavelength decreases to times its original value. (Note: enter answer as a decimal)arrow_forward
- Define Visible rays.arrow_forwardYou wish to observe an astronomical object whose spectrum peaks in the UV. This object is bright and you want to study its absorption lines, so you need a detailed spectrum. Please describe the type of telescope (refracting vs reflecting) you would want to use as well as where it should be located for best effect. You should also consider if you need a large telescope or a small one would suffice.arrow_forwardGive at least three reasons why reflecting telescopes are superior to refractors.arrow_forward
- Calculate the index of refraction in a substance where the speed of light is 1.2x108m/s? The angle of incidence from air into a substance is 30°. The angle of refraction in the substance is 18°. What is the speed of light in the substance?arrow_forwardHow does the speed of light in empty space compare to the speed of light in air? Some colors travel faster in air, while others travel faster in empty space. Light cannot travel through empty space. Light cannot travel through air. Light is slightly faster in empty space. The speed is exactly the same. Light is slightly faster in air.arrow_forwardwhat is the reason some spectra show the full range of colors while some only give a few colored lines?arrow_forward
- A woman standing on a cliff is watching a motor boat as the boat approaches the shoreline directly below her. If the womans eyes are 250 feet above the water level and if the boat is approaching at 30 feet per second, how fast is the angle of depression of the boat from the womans eyes changing when the boat is 250 feet from the shore?arrow_forwardDoes one of these visible light waves move faster than the others? Which one is fastest and why? I need help because I think it is wave C but I am not confident. Thanksarrow_forwardI need help solving this problem. Please explain in detail and make sure the solution is fully viewable.arrow_forward
