- 20. DETAILS OBINPHYS8 9.P.001. ASK YOUR TEACHE ........................ Suppose a beam of red light from an He-Ne laser (2 = 633 nm) strikes a screen containing two narrow slits separated by 0.210 mm. The fringe pattern is projected on a white screen located 1.10m away. Find the distance in millimeters between adjacent bright areas near the center of the interference pattern that is produced. mm Submit AnswerThe answer is not 23.75. Please helpA 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?…
- 3. Calculate the polarization loss factor (PLF)...in db and dimensionless of an antenna whose electric field polarization is expressed as: E = (ax+ ay)E(r,0,0), when the electric field of the incident wave given by E, = ax E, (x, y)e-k=9. Consider TE oblique incidence with 30 degree incidence angle from the air (n=1) to the semiconduc tor (n=3.5). The optical wavelength is 1.5 µm. We want to coat a thin film on the semiconductor to achieve zero reflection for this particular case. The coating material is with the refractive index n and the thickness d. (1) What is the power reflectivity of the interface without the coating. (2) Please determine the required d and n to achieve zero reflectivity.Explain the interaction of light with thin films, including the conditions for constructive and destructive interference.
