- Explain what the ionosphere is and how it interacts with some radio waves.arrow_forwardIf you live in a region that has a particular TV station, you can sometimes pick up some at its audio portion on your FM radio receiver. Explain how this is possible. Does it imply that TV audio is broadcast as FM?arrow_forwardReview. A microwave oven is powered by a magnetron, an electronic device that generates electromagnetic waves of frequence 2.45 GHz. The microwaves enter the oven and arc reflected by the walls. The standing-wave pattern produced in the oven can cook food unevenly, with hot spots in the food at antinodes and cool spots at nodes, so a turntable is often used to rotate the food and distribute the energy. If a microwave oven intended for use with a turntable is instead used with a cooking dish in a fixed position, the antinodes can appear as burn marks on foods such as carrot strips or cheese. The separation distance between the burns is measured to be 6 cm 5%. From these data, calculate the speed of the microwaves.arrow_forward
