"Microwaves" are radio waves.
The wavelengths of the signals used to broadcast radio and TV to household and automotive
radio and TV products are longer than the wavelengths of the signals used for point-to-point
microwave communication.
They're also longer than the electromagnetic energy used in the microwave oven to cook a turkey
in 13 seconds, and longer than the wavelength of the signals to the GPS receiver in your car.
They're also longer than the wavelength used to operate your cellphone, and longer than the
wavelength of the signals that bring 900 channels of satellite TV directly to the little dish on the
corner of your house.
AM radio waves are. This has nothing to do with the science or Physics of AM or TV.
It's only the result of the frequencies where they happen to operate.
In the USA, commercial AM radio broadcasting takes place on frequencies between
0.55 and 1.7 MHz, whereas TV broadcasting starts at 54 MHz and goes up into the
stratosphere from there.
Higher frequency means shorter wavelength.
Along the same lines . . . commercial FM radio broadcasting is carried on at
frequencies between 88 and 108 MHz. That's higher than some TV channels
and lower than others.
Radio waves and microwaves have longer wavelengths. Think about it, you cannot see radio or microwaves.
They are much much longer.
Much much much longer.
yes
If they are travelling throught the same medium, then no. They are both types of electromagnetic waves and so they travel at the same speed (in a vacuum, that velocity is around 300,000,000 metres per second).
receive broadcast signals
Broadcasting stations use television satellites to send their signals around the world.
The waves used to broadcast radio signals are called RF waves and these generally lie in VHF and UHF band of electromagnetic spectrum.
It is used for sending wireless signals over the Very High Frequency band of radio. This band is mainly used for television signals. It can also be used to modulate a television signal in a single cable.
TV broadcast signals are in the VHF & UHF radio bands, shorter than most of the radio bands but longer than the microwave band.

"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).
Television communication uses short wave radiation for communication. This is also used for radios. Most technology today relies on wavelengths which are overall reliable and efficient.

This is also the reason AM radio signals travel around buildings and hills better than light waves (or even TV signals). The longer wavelengths diffract around obstacles that the shorter wavelengths cannot, regardless of the type of wave.
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
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
A satellite dish works to receive signals and burn them up at its burn point,due to the high strength of the signals it can work in doors because the signals can penetrate through the walls,"BUT" this greatly reduces the signal strength hence leading to low efficiency,and since it also sends out signals, weak signals will be sent out due to the effect of the walls and some other impenetrable metallic materials like lead and other heavy metals with high relative molecular masses.

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.
Egyptians, like the rest of the world, (Mexicans, Italians, Japanese, etc) receive over the air TV signals, satellite TV signals, and cable TV signals. So the answer to this astoundingly stupid question is YES!
