- 4. What is the critical angle for light passing from diamond to air if the index of refraction of diamond is 2.42?Why the Sun and the surrounding sky appears red during Sunrise and Sunset?Choose the correct statement. For light, we can call white a tertiary color because RED + BLUE + GREEN = WHITE. O For light, we can call white a tertiary color because GREEN + MAGENTA = WHITE. O We cannot call white a tertiary color. For light, we can call white a tertiary color because YELLOW + MAGENTA + CYAN = WHITE.
- Can water waves be reflected and refracted? Give examples. Does Huygens’s principle apply to water waves? Explain.8. b) Ô d) Consider a yellow piece of construction paper. What color will the paper appear if you shine green light onto it? Explain. What if it is illuminated with magenta light? Explain. Under what light conditions would the paper look black? Explain. The figure below shows a "color wheel" for three light sources illuminating a yellow screen. The top light source is red, the bottom-left is blue, and the bottom-right is green. Complete this figure by indicating the color that will be seen in each of the seven regions on the screen. Explain your reasoning, discussing how you used your answers above and how you determined the color of the regions not described above.
