Why are humans not able to see,feel or hear radio waves? We are sensitive to the rest of the waves in the EM spectrum. If EM waves are composed of oscillating magnetic and electric fields, why am I not electrocuted by the electric constituent of the Radio waves?
In: Physics
Radio waves have wavelengths of several feet, so humans are virtually transparent to radio waves, like glass is transparent to visible light. If you have a piece of conductive metal the right length (an antenna), the waves WILL interact and make electricity move in it. Because the signal is so weak and humans are not as conductive as metal, we don’t notice any effect.
But if you stand really close to a powerful transmitting antenna, it can heat up your body (microwaves were discovered this way when a technician noticed the chocolate being melted in his pocket).
