- 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.arrow_forwardThe 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_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

What color would you predict this wavelength to be?arrow_forwardWhat is the range of frequencies used for TV transmission? What is common between these waves and light waves?arrow_forward8. Suppose a noise has an intensity spectrum level of 30 dB and a bandwidth of 100 Hz. What is the total band level (i.e., measured SPL) of the signal? * 10 dB 50 dB 130 dB O 70 dB 9. Now suppose I reduce the bandwidth of the signal in #8 in half, reducing the frequency range it covers. What will happen to the sound level? * O It will increase by 3 dB O It will increase by half O It will double O It will decrease by 3 dB O It will remain unchangedarrow_forward
- 1. 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_forwardWhich of these does NOT describe an effect of the atmosphere on astronomical observation? Answers: A. Filtering out infrared and other wave bands. B. Unsteady or turbulent air. C. Decreased light-gathering power. D. Scattering light from nearby cities. E. Weather conditions.arrow_forwardTransmission (%) 100 B 21 150 200 250 500 1000 B. Infrared light C. Yellow light D. Blue light 1500 2000 Wavelength (nm) 2500 3000 3500 Based on the transmission plot shown here, what kind of light do you think is least likely to be transmitted? (Make sure you can see the values of the wavelength along the horizontal axis. Enlarge the image or screen if you need to.) A. Red lightarrow_forward
- The main reason for creating an interferometer with two separate radio dishes is to a. monitor two different radio wavelengths simultaneously. b. increase the intensity of the detected signal. c. compare objects in two different directions simultaneously. d. increase the resolution in the data.arrow_forward22. A TV screen has 3,000,000 pixels. If the screen shows an image that is 1/4 yellow, 1/2 cyan, and 1/4 magenta. How many of each color light are lit up?arrow_forwardA particular object appears to be red. The reason it appears red is: 1. It absorbs only red frequencies as they hit. 2. It reflects only red frequencies as they hit. 3. It absorbs red frequencies more than other frequencies. It reflects red frequencies more than other frequencies. 4. 5. It emits red frequencies more than other frequencies. 6. Not enough information.arrow_forward
