t or other electromagnetic & When l h oss a given region, (a) what is it that oscillates light (or radiation) trav s across ib) What is it that is transported? o space sailing, which is a proposed alternative for z In space sailing, w ort to the planets, a spacecraft carries a very ransp transport lunge sail. Sunlight striking the sail exerts a force, accel- rating the spacecraft. Should the sail be absorptive or reflective to be most effective? What does a radio wave do to the charges in the receiv- ing antenna to provide a signal for your car radio? s. Does a wire connected to a battery emit an electromag netic wave? l. Suppose a creature from another planet had eyes that were sensitive to infrared radiation. Describe what it would see if it looked around the room that you are now in. That is, what would be bright and what would be dim? Il. Why should an infrared photograph of a person look different from a photograph taken using visible light?
Explanation / Answer
the antenna in the car recieves the radio waves and the electron inside the antenna start motion back and forth depending according to the frequency of the radio wave and thus recieves the same signal as transmitted by the transmitter antenna
