Please 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?

"50 Shades of Grey": What is the true color of matter? Is color an inherently intrinsic property? Why do substances have the color that they do? Why does the eye see the color that it does? What is the physics of color?
It took scientists a long time to reconcile the dual nature of light, which led to the idea of the duality of matter. Will it be possible to see the dual nature of light at the same time? Briefly explain your answer.
You learned how light and matter interact. Matter can transmit, absorb, and reflect light. Visible light includes a range of colors and is the only part of the electromagnetic spectrum that we can see. Read the scenario about light and answer the questions in complete sentences. You have a blue backpack and you look at it through blue glass. What color would the backpack appear to be? Suppose you took the same blue backpack and looked at it through red glass, what color would the backpack appear to be? Explain your answers.
If a star has a peak wavelength of 450 nm (violet). What is the corresponding frequency of this wavelength? What is the corresponding temperature? What is the photon energy for a single photon of light (450 nm)?
Note that a “gray” object under a red light can reflect the same light as a “red” object under white light. If we want our color perception to remain constant under different lighting conditions, should we base perceived color on (circle one) 1) the spectrum of light reaching the eye from the object (the signal)? or X the percent of light the object reflects at different wavelengths (the reflectance)
A beam of white light hits a prism and is dispersed into the its spectral components – red, orange, yellow, green, blue, indigo, and violet. If a second prism is placed so that only the red band of light can pass through, what would you predict would occur and why?
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?

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? Explain
What is the energy of light with a wavelength of (2.50x10^2) nm? Answer to 3 significant figures in scientific notation. Unit is case sensitive. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Answer x10 units
Everyone knows the 7 colors of the rainbow: Red, Orange, Yellow, Green, Blue, Indigo, and Violet. Are rainbows always composed of these colors in the same order? If so, which color makes up the inside arc of the rainbow (the band of color closest to the ground), and why?
A prism can split light up into its colors because the speed of the different colors of light in glass varies slightly, with purple being the slowest, and red the fastest. White light is shined through a prism, which of the following describes the light that emerges from the prism? After passing through the triangular prism, the light becomes triangular shaped The light splits into its colors, with purple bending the most Only white light emerges from the prism O The light splits into its colors, with purple bending the least
