"electromagnetic spectrum/read-and-respond/?assig radio waves have wavelengths that can be as long as a football field. they travel to earth from places like the sun and jupiter. radio waves have the longest wavelength, lowest frequency and lowest energy. they are used in communication for technology like cell phones, radio and television. radio waves aren't sound waves, so you can't actually hear them. there are charged particles in the earth's atmosphere that reflect radio signals. the waves carry signals thousands of miles to a receiver that converts that signal to sound. which of the following correctly describes how radio waves are transmitted and converted into sound? ? 1. waves convert radio signals into sound. 2. particles in earth's atmosphere carry sound. 3. receivers reflect the sound. 1. receivers carry radio signals. 2. particles in earth's atmosphere reflect the signals. 3. waves convert the signals into sound. 1. waves carry radio signals. 2. receivers convert them into sound. 3. particles in earth's atmosphere reflect the sound. 1. waves carry radio signals. 2. particles in earth's atmosphere reflect them. 3. receivers convert them into sound. ? d Get the answer
