- The Sun appears to be red as it sets because:1. Air absorbs red light less than other frequencies (i.e., acts like a red filter).2. The sunlight has a red shift when you're moving fastest away from it.3. The Sun cools down to 5000 K each evening.4. Light is refracted as it enters the atmosphere.5. The Sun dies in a glorious fireball each evening and is reborn each morning.6. None of the above.arrow_forwardYou 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.arrow_forward5. Can sound waves be polarized? What about ocean waves or waves propagating on a string? What fundamental characteristic allows waves to have a polarization? 6. Approximately how long does it take a light wave to travel from your head to your toes? Assume you are standing straight up. 7. The spacecraft that have landed on Mars send their information to the Earth via radio waves. How long do these waves take to reach the Earth when (a) Mars is at its closest to the Earth? (b) Mars is farthest from the Earth? This time delay is important for NASA when it sends a spacecraft to Mars.arrow_forward

The transcript should be able to be used for a 2-3 minute long video. Why is the sky blue? Why do we see a rainbow when the sun shines after rain? Why does a spoon seem to bend in a clear glass of water? Why are there rainbows in oil spots on the driveway? How can light help us measure small distances, such as the thickness of a single piece of hair? How do anti-glare coatings on eyeglasses work?arrow_forward1. The gas cloud known as the Crab Nebula can be seen with even a small telescope. It is the remnant of a supernova, a cataclysmic explosion of a star. The explosion was seen on earth on July 4, 1054 AD. The streamers glow with the characteristic red color of heated hydrogen gas. In a laboratory on the earth, heated hydrogen produces red light with a frequency 4.568 × 10¹4 Hz; the red light received from the streamers in the Crab Nebula pointed toward the earth has frequency 4.586 × 10¹4 Hz. (a) Estimate the speed with which the outer edges of the Crab Nebula are expanding. Assume that the speed of the center of the nebula relative to the earth is negligible. (b) Assuming that the expansion speed has been constant since the supernova explosion, estimate the diameter of the nebula. (c) The angular diameter of the Crab Nebula as seen from earth is about 5 arc minutes (1 arc minute = 1/60 of a degree). Estimate the distance (in light years) to the Crab Nebula and estimate the year in…arrow_forward
- What is the range of frequencies used for TV transmission? What is common between these waves and light waves?arrow_forwardA constellation of radar satellites in LEO orbit is being used to monitor the open ocean. The system collects two SAR images of the same area separated by a few hours in time. In the first image, the ocean appears dark, but in the second it appears brighter. What is the most likely cause of this difference? A. An oil spill occurred between the images, making the water more smooth. B. The wind speed increased between the images, causing waves to form on the ocean surface. C. The first image was collected at an oblique angle, while the second was taken looking straight down (a nadir view). D. The collection geometry changed between images resulting in a Doppler shift of the signal intensity.arrow_forwardWhy is the sky blue? O Our eyes are not very sensitive to violet light. O The molecules and atoms in the atmosphere strongly scatter blue light. O The molecules and atoms in the atmosphere absorb all other wavelengths of visible light.
