- If 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.Which statement below is false? O The wavelength of light is the distance between two corresponding points in the wave pattern O The frequency of the light is the number of waves that pass a given point in a second The higher the frequency of light, the longer the wavelength The frequency of light increases as wavelength decreases The higher the frequency of light, the greater its energyT or F? Huygens’s principle provides a foundation for wave optics and can explain observations such as light diffraction, but it fails to provide an explanation for the rules of geometric optics.
- As a light ray travels from vacuum (n = 1) to a medium where refractive index gradually increases, (n >1 but not uniform, which of the following properties decreases gradually ? Group of answer choices Wave crest Wave trough Wavelength FrequencyA water break at the entrance to a harbor consists of a rock barrier with a 67.0 m wide opening. Ocean waves of 43.0 m wavelength approach the opening straight on. At what angle (in degrees) to the incident direction are the boats inside the harbor most protected against wave action?A cold distance planet has an atmosphere of hydrogen (speed of sound = 1320 m/s) over a liquid ocean of carbon dioxide (speed of sound = 259 m/s). A sudden shift in the rocky crust beneath the ocean creates a sound wave that heads toward the surface at an angle of 7 degrees. At the surface, the wave is refracted with a refraction angle of . . . Group of answer choices 49 degrees. 38 degrees. The wave undergoes total internal reflection. 80 degrees.
