A blue-hot star is about twice as hot as a red-hot star. But the temperatures of the gases in advertising signs are about the same, whether they emit red or blue light. What is your explanation?
When astronomers look at the spectrum of the Sun, they noticed that the light from one edge is slightly blue-shifted, while light from the opposite age is slightly red-shifted. What does this tell you about the Sun?
Red sun rise occurs for the same reason as red sunsets. But sunsets are usually more colourful than sunrise—especially near cities, what is your explanation ?

- Go outside on a clear night, wait 15 minutes for your eyes to adjust to the dark, and look carefully at the brightest stars. Some should look slightly red and others slightly blue. The primary factor that determines the color of a star is its temperature. Which is hotter: a blue star or a red one? Explainarrow_forwardIf you see a “violet-hot” star, you can be certain its peak intensity is in the ultraviolet range. Why is this?arrow_forwardIf a star gives off light at a peak wavelength of 6.80x10-7 m. What would be the temperature of this star in Kelvin?arrow_forward
- Why does the sun’s radiation output match that of a blackbody?arrow_forwardIf you observe a star’s blackbody spectrum twice, once from Earth and once from a space shuttle above Earth’s atmosphere, what will you see? An absorption spectrum from Earth and a continuous spectrum from space An absorption spectrum from space and a continuous spectrum from Earth An absorption spectrum from space and an absorption spectrum with more absorption lines from Earth An absorption spectrum from Earth and an absorption spectrum with more absorption lines from spacearrow_forwardPlease answer the question about light and color: Which line is easier to see under red light, the red or the black line? Why? What makes red ink appear red? When red ink is illumined by blue light, is most of the light absorbed or reflected? When illumined with red light, why is red ink on white paper more difficult to see than black ink?arrow_forward
- Suppose you are working with a photosensitive material that you know is sensitive to green light, but you do not know whether it is sensitive to any other colors. If you must work with the material in some kind of light that you can see, what would be more likely to damage the material, red light of high intensity, or purple light of low intensity?arrow_forwardWhy do opaque materials become warmer when light shines on them?arrow_forwardKrypton (36), Mercury (Hg 80), Hydrogen (H 1), Silicon (Si 14), and Gold (AU 79) The Three primary colors of light are: ____ ____ ___ _____ ____ ___ 6. (7) How are spectral patterns used to identify specific light sources? ___________________ ______________ 7. Using the diffraction grating from the kit observe various light sources and view it with the diffraction grating. Identify the colors you see and identify if any one color is dominant. (Check flashlights, lamps, household lights, refrigerator lights are usually incandescent, car lights, etc… to find the needed light source.)
