Step by step
Solved in 3 steps
- Prior to the switch to digital television broadcasting, and to the popularity of cable television, many homes had outdoor TV antennas. TV-reception antennas for VHF (channels 2 through 13) were constructed with cross wires supported at their centers, as shown in the figure below. The ideal length for the cross wires is one-half the wavelength to be received, with the more expensive antennas having one for each channel. Suppose you measure the lengths of the wires for channels 12 and 6 and find them to be 0.208 m and 0.958 m long, respectively. What is the frequency for channel 12?Hz What is the frequency for channel 6?HzFind the largest wavelength (in nm) of light falling on double slits separated by 7.5o µm for which there is a second-order maximum. nm Is this in the visible part of the spectrum? Yes NoA beam of light with a wavelength of 511 nm strikes a pair of slits with a seperation of 0.1 mm and a distance of 1 from a screen. What is the distance between bright spots in mm?
- 1. (a) What is the highest-order maximum for 400 -nm light falling on double slits separated by 25 µm? Hint: Is there a limit on how many bright and dark bands appear on a pattern? (b) What part of the EM spectrum does this wavelength belong to? Visible Region/Ultraviolet O Infrared X-raysA microwave dinner has the instructions listed below. In this problem, you will explain how following the instructions affect the heat transfer into the meal. The meal starts off frozen, and is covered with a thin piece of plastic "film" or covering when it is taken out of the box. The vegetables are separate from the beef and potatoes.) Instructions: 1. Cut slit in film over vegetables. 2 Microwave on high 4 minutes. 3. Turn bock film from beef and potatoes. Stir beef and potatoes. Replace film. Return tray to microwave oven. 4. Microwave on high 3 minutes. 5. Let stand 2 minutes in microwave oven. Stir beef and potatoes. a. How does each of the steps above (cut slit in film, stir beef and potatoes, etc) affect the heat transfer to the food? Make sure to consider conduction, convection, and radiation where appropriate. b. The instructions ask you to stir the beef and potatoes, but not the vegetables. From this, what can you tell about how each type of food receives and transfers heat?…
