There is more than one wavelenth for Television and Radio. It's a region. Scroll down to related links and look at "TV wave region".
Television waves are radar waves or radio waves simply because they are useful for long term communication and are readily reflected by the ionosphere. Microwaves are used for short term communication very rarely and for heating purposes. All three however travel at the same speed that is 299,792,468 m/s.
wavelength = velocity/ frequency wavelength = 330/256 wavelength = 1.29 (to 3 sig fig) 1.30
Wavelength and frequency are inversely proportional.
It depends what the wavelength and frequency of the wave is. The wavelength is the distance between either two minima, or two maxima.
The peak wavelength, is connected to the temperature of the objects. we have short peak wavelength when the temperature is high.
The peak wavelength of the IR diode used in TV remotes are usually around 940 nanometers.

Wavelength = speed/frequency = 299,792,458/810,000 = 370.114 meters.It makes no difference whether it's AM, FM, TV, 256QAM, modulated, or CW.
Good luck, Greater wavelength=TV. frequency= the number of wave cycles(peak, trough, peak) per time unit. The higher the frequency, the more times the wave cycles, and the shorter the wavelength. Greater Energy=Ultraviolet lamp. By Placks constant, E(energy) =h(planck's constant which is the energy of a photon divided by it's frequency) / f(the frequency of that photon). Planck's constant is almost irrelevant, so the greater the frequency, the greater the energy. Greater frequency=Ultraviolet lamp. Planck's constant and light spectrum. Greater Momentum= Ultraviolet lamp. Electron diffraction, Wavelength=h(planck's constant) / momentum. rearrange it as M=h/W. The greater the wavelength, the smaller the momentum, and visa versa.
Yes, the shorter the wavelength, the higher the energy. Gamma waves have the shortest wavelengths of all the electromagnetic radiation waves and carry the greatest energy. Radio and TV waves have the longest wavelengths and carry the least energy.
When you listen to the radio, watch TV, or cook dinner in a microwave oven, you are using electromagnetic waves. Radio waves, television waves, and microwaves are all types of electromagnetic waves. They differ from each other in wavelength. Wavelength is the distance between one wave crest to the next. For more info, click the link below.
Infrared is just a colour of light, but one that our eyes cannot see. You can think of the different colours of light as having different wavelengths. Our eyes can see light with wavelengths between blue (short wavelength) and red (long wavelength). Infrared has an even longer wavelength than red light, but our eyes can't see it. If you hold your hand up to a fire, it feels warm. This is beause very long wavelength infrared warms you up. An infrared ray is invisible to your eye, but technologists can build sensors that can detect it. When you use your TV remote control to change a channel on a TV, selecting the channel on the remote tells the device to send out infrared light of a particular frequency. The light from the remote control (invisible to us) is picked up by a sensor on a TV, and depending on the frequency of the infrared, the TV decides what channel to select.
Infrared rays are electromagnetic waves with a wavelength longer than the wavelength of visible 'red' light [or you could say they have a lower frequency than red light]. Infrared 'light' is used in TV remote controls to transmit information to an infrared receiver on the TV, and also in security systems to create an invisible 'light beam' that when broken, will send a signal back to the system.
The frequency is equal to the sped of light divided by the wave length.The speed of light is 300000 km/s and the wavelength (λ) is 3.56 m or 0.00356kmSoF=C/λF= (3000000km/s)/(0.00356km)F=842696629.2134831Hz -> 84.26967MHz
They go by many names in everyday life. Here are a few of them: -- AM -- FM -- TV -- GPS -- cellphone signal -- wireless -- microwave -- heat -- red light -- green light -- blue light -- tanning rays -- X-rays
In the entire spectrum of electromagnetic waves, microwaves and radiowaves (microwaves are sometimes classified under radio waves), have the longest wavelengths, and the lowest frequencies (and therefore, energy).
