Both radio waves and light are electromagnetic waves; their main difference is their frequency. Radio waves are created by the acceleration of electrons in a radio antenna, and light waves are created by the oscillations of the electrons within atoms.
What Are the Principal Differences Between a Radio Wave and Light?
Radio waves and light are both electromagnetic radiation, but they differ in a few key ways. For one, radio waves have much longer wavelengths than light waves, which means they carry less energy.
This makes them safer for human exposure, but it also means they can‘t be used for tasks like visible communication or photography.
Additionally, radio waves can penetrate materials like walls and buildings that light cannot, making them ideal for applications like radar and radio astronomy.
Finally, while light waves are produced by accelerating electrons, radio waves can be generated by a variety of methods including moving charges, magnetic fields, and even the rotation of the Earth.
