IR Infra red rays
We all almost use An IR remote controller to use operate a TV OR DTH OR any other electronics Gadgets in out home but ever you think how this process works means when you press any key in front of your TV then it react as per command given by you …..
Lets know how it happen ..in very simple words , no more technical depth..
A IR Remote Controller works in a line of sight “means the operating device must be placed in front of Remote controller” as a Transmitter (means will send signal from itself) and transmit an IR (Infrared) modulated (coded) signal (binary command codes in Electronics Engineering language) once any keys of the Remote controller pressed by you then a signal corresponding to pressed key will transmit and carrying a command which hit to the IR Receiver of electronics Device which is mounted in the front panel of your TV (mostly hidden not seen in front side of device) or any Device it must be in front of you ( it can be TV, STB , DTH , AC , etc ) and then receiver demodulates (decode) the receiving signal and activate the desired required function/command sent to the receiving device through the inbuilt Programmed microcontroller . All this activity happens in a very short time in micro seconds. you can see a little glass bulb type component in front of every IR remote and that is mainly a IR LED which transmit the signal towards to any receiving device….and rest of the all above said process happened
I think in the ultraviolet region of the electromagnetic spectrum.
Radio waves have a lower frequency than microwaves in the electromagnetic spectrum. They have the lowest frequency and longest wavelengths of all the electromagnetic waves.
The energy of EM radiation depends on its frequency, and the lowest frequency corresponds to the lowest energy. Radio waves are at the low end of the energy and frequency spectrum.
Extremely low frequency (ELF) radio waves. They can have wavelengths of over 60,000 miles (100,000 km) and frequencies from 3 to 300 Hz.
The part of the electromagnetic spectrum with the lowest frequency and longest wavelength is radio waves. They are used for communication, broadcasting, and radar.
I think in the ultraviolet region of the electromagnetic spectrum.
The lowest frequency is effectively zero and this would be in the extremely low frequency (ELF) band in the sub-radio range of the electromagnetic spectrum.
Radio waves have a lower frequency than microwaves in the electromagnetic spectrum. They have the lowest frequency and longest wavelengths of all the electromagnetic waves.
Gamma rays
Frequency determines this.
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
The answer is electromagnetic spectrum
Gamma rays
The energy of EM radiation depends on its frequency, and the lowest frequency corresponds to the lowest energy. Radio waves are at the low end of the energy and frequency spectrum.
sunlight
Electromagnetic spectrum is formed due to the difference of wavelengths and frequency of electromagnetic radiations as they are orderly distributed.
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
