The explanation given in your textbook for the color of the setting Sun should apply equally well to the rising Sun, since sunlight travels the same distance through the atmosphere to reach your eyes at either sunrise or sunset. Typically, however, sunsets are redder than sunrises. Why? (Hint: Particles of all kinds in the atmosphere contribute to scattering.)
You are in a room lit only by yellow light. A pillow in that room looks red you. (your eyes red +
green light as yellow, your eyes see red + blue light as magenta; your eyes see green and blue
light as cyan)
a) What colors of light is the pillow reflecting in the yellow room? What colors of light is the
chair absorbing in that room? Explain
b)
You then move the pillow into a room lit only by blue light. The pillow now looks blue.
What colors of light is the pillow reflecting now? What colors is it absorbing? Explain
c) What color will the pillow be in the sunlight? explain

- The color of the setting sun should apply equally well to the rising sun, since sunlight travels the same distance through the atmosphere to reach your eyes at either sunrise or sunset. Typically, however, sunsets are redder than sunrises. Why? (Hint: Particles of all kinds in the atmosphere contribute to scattering.)arrow_forwardA student is sitting outside on a sunny day looking at a book with a blue cover. She is explaining to her friend how she can see the book cover as blue. She said: "I can see the book cover as blue because light from the sun travels in straight lines to the book. The white light from the sun contains red, green, and blue light. When it strikes the book cover, the blue light is reflected at equal angles, while the rest of the colors are absorbed in the book cover. The reflected blue light then enters my eye, and I see the book cover as blue." Evaluate her explanation to determine whether it is good or poor, by choosing one of the following responses: O It is problematic because the idea that "the white light from the sun contains red, green, and blue," is not correct. It is problematic because the idea that "mostly the blue light energies are reflected at equal angles," is not correct. It is good because all the ideas are correct scientific ideas, and none of the important ideas are…arrow_forwardWhy the color be created different by mixing red +green light and by mixing red +green paint?

- Does the refractive index of a certain material depend on the color of light incident on it? Explain.arrow_forwardCheck all boxes that apply. Ultraviolet radiation: is invisible to human eyes. O travels at a speed of 3x10®m/s through all mediums. O has a higher frequency than microwave radiation. O has a higher frequency than blue light. O has a longer wavelength than radio waves. O has a shorter wavelength than blue light. O has a shorter wavelength than gamma rays. O cannot enter our atmosphere. does not experience total internal refraction.arrow_forwardIf you were to observe the sunset on the Moon, would you see the space around the sun as red, like you do on earth? Yes, because the color of light is independent of where you are. No, you would see it blue because of scattering of light. It would depend on the time of the day when you look at the sky. You would not because there is no atmosphere on the moon to scatter the light. You would not because the moon absorbs all the colors of light. You would see it black because the moon reflects all the colors. Yes, you would see it red like on the earth because both the moon and the earth are spehrical.arrow_forward
