How does the electromagnetic waves store information, what makes these waves to store. (this may be a stupid question but i need to know how)
Thanks.
Thanks.
Electromagnetic waves are a type of energy that is created by the oscillation of electric and magnetic fields. They are invisible to the human eye, but can be detected and measured using specialized equipment.
Electromagnetic waves store information through variations in their amplitude, frequency, and phase. These variations can be manipulated to carry different types of information, such as sound, images, and data.
Electromagnetic waves are used to store information because they have several advantages over other forms of energy. They can travel long distances at the speed of light, can be easily manipulated and detected, and do not require a physical medium to propagate.
Electromagnetic waves are generated by sources that produce oscillating electric and magnetic fields, such as antennas and electrical currents. These waves can also be produced artificially through devices like radios and cell phones.
Some common uses of electromagnetic waves for storing information include radio and television broadcasts, cellular communication, WiFi networks, and satellite communication. They are also used in medical imaging, radar technology, and GPS systems.
