Do mircrowaves have the longest wavelength?
"Microwaves" are radio waves ... those with wavelengths of 10 centimeters or less.The wavelengths of the signals used for point-to-point microwave communicationare shorter than the wavelengths of the signals used to broadcast radio and TV tohousehold and automotive receivers, and also longer than the wavelength of thesignals to the GPS receiver in your car.Microwaves are shorter than the wavelengths used to operate your cellphone.The microwave range of frequencies (wavelengths) is used for the signals that bring900 channels of satellite TV directly to the little dish on the corner of your house.Here's an interesting factoid: Technically, the box in your kitchen that heats theleftover meatloaf in 13 seconds is not a "microwave" oven. "Microwave" officiallyrefers to frequencies of 3 GHz and higher (wavelength 10 cm and less). The handykitchen appliance operates at the frequency assigned to it, which in the USA is2.450 GHz (12.24 cm).
What are the properties of infrared waves?
Infrared signals are the electromagnetic radiations with wavelengths longer than the visible light but shorter than the radio waves. Infrared signals, with frequencies from 300 GHz to 400 THz (wavelengths from 1 mm to 770 nm) can be used for the short range communication. Infrared signals, having high frequencies can not penetrate into the walls.By Robert John Smith
Which is shortest frequency 10mhz 100mhz 1ghz 100ghz?
100MHz Wavelength(m) is inversely proportional to frequency (Hz) Use the equation λ=v/f (Wavelength=velocity/frequency) For the velocity just use the value 1 as since both waves will be through the same medium it doesn't matter 0.000001m = 1ms-1 / 10,000,000Hz 0.0000001m = 1ms-1 / 100,000,000Hz
If infrared waves can move information through the air, what is the advantage of sending their signals through networks of cables?
Cables transmit infrared waves over longer distances. -Apex :)

How do you get the picture from satellites?
The satellite takes a picture and sends it by signals.

How radio waves detect signals from other parts of the universe?
they use telescopes that find certain wavelengths
Optical signals in optical cables have short wavelength why?
Because the attenuation of the fiber is much less at those wavelengths.

What type of electromagnetic wave does radio receive?
Radio waves have the longest wavelengths in the electromagnetic spectrum. These waves can be longer than a football field or as short as a football. Radio waves do more than just bring music to your radio. They also carry signals for your television and cellular phones.
What is the logical explanation of how colour comes to your eyes?
Light rays of differing wavelengths enter the eyes and strike the retina which converts them into electrical signals, these signals are sent to the brain where they are reinterpreted as colours and images.
Which light carries data signals for short distances and with a clear line of sight?
Infrared light
How do you people use radio waves?
Radio waves have the longest wavelengths in the electromagnetic spectrum. These waves can be longer than a football field or as short as a football. Radio waves do more than just bring music to your radio. They also carry signals for your television and cellular phones
The inability of telephone cables to carry signals across long distances was solved by the invention of the electronic?
Amplifier
Why were long-range radio signals important?
so people could communicate over long distances
