There are energy forces that you can’t see, some of which are electromagnetic waves. These aren’t the vibrations created through the mass of solid material but are created through the fluctuations between magnetic and electric fields. There are a few different types of electromagnetic ways, with most recognizing radio waves infrared signals, microwaves, gamma rays, x-rays, and ultraviolet rays as examples. Using an rf directional coupler, the electromagnetic power can be harnessed and transferred between circuits. All of these waves travel at the speed of light, but each has a varying form of energy.
This is probably one of the most apparent and heavily used applications of the electromagnetic waves. While commonly used to heat and cook food products, these waves can also be used for communications. Since the waves aren’t too different from radio waves, it can be used to extend television signals to further distances.
The waves are used for communication purposes. Your car radio works with these waves, but these are also the waves that power mobile phones. Your voice is carried through radio waves and decoded. Radar technology also relies on radio waves and has become vitally important to the military. Less popular with the majority of individuals is the use of radio waves to operate the speed guns and speed cameras of law enforcement.
The sun is a natural producer of ultraviolet waves, and prolonged exposure has been linked to increased risk of skin cancers. The same UV rays that are used to create a golden tan can also be damaging to the skin. However, UV rays have a positive use as well. Ultraviolet waves are used to disinfect and sterilize medical instruments. These rays can kill viruses and bacteria.
Though they aren’t seen to the naked eye, the influence and energy of electromagnetic waves can be seen across industries and common household items.
