Question 15 (5 points) Listen A physics teacher is reheating her leftover pizza lunch in the very old teacher breakroom microwave. The microwave is so old that it doesn't even turn the food as it cooks. When the teacher takes her food out and eats it, she discovers that parts of the pizza are scalding hot, while other parts are still very cold. She explains to the students that a microwave works by producing standing waves that result in heating. She asks the students to explain why some parts of the pizza are hot while others are still cold. Below are their responses: Student A: "The waves travel across the piece of pizza and then are absorbed by the sides of the oven. Since the pizza never moves, only the parts of the slice that the waves traveled through were heated, and the rest stayed cold." Student B: "At the nodes of a standing wave, the wave is shaking very rapidly, causing those parts of the pizza to get hot. At the antinodes, the wave is not shaking much at all, causing those parts of the pizza to stay cold." Student C: "The waves travel across the piece of pizza and then are absorbed by the sides of the oven. Since the waves have crests and troughs, parts of the pizza are not touched by the wave and remain cold." Student D: "At the antinodes of a standing wave, the wave is shaking very rapidly, causing those parts of the pizza to get hot. At the nodes, the wave is not shaking much at all, causing those parts of the pizza to stay cold." Which student has the correct claim about why the food was not evenly heated? 1) Student A O 2) Student B 3) Student C 4) Student DQuestion 2 (5 points] Listen Which of the following is not a primary color of pigments? 1) yellow ( 2) cyan (3) magenta O 4) orangeQuestion 6 (5 points] Listen What color would be needed to mix with yellow to produce white light?
