No, in a vacuum infrared radiation has a wave length of between 10^-6 and 10^-2 while radio waves have 10^-1 and beyond and long radio waves have a length of 10^3 and beyond.
The longest wavelength corresponds to long wave radio, I think the longest used is about 2000 meters. The shortest are gamma rays, which occur in radioactivity, these are from about 10-11 meters down.
Frequencies in the range 30 PHz (PetaHertz) to 750 THz (TeraHertz), Wavelengths from 10 nm to 400 nm.

"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).
There are seven electromagnetic waves; radio waves, microwaves, infrared, visible light, ultraviolet, X rays, and gamma rays. Radio waves are transmitted through radios (duh) and TVs. They have wavelengths greater than 0.001 meters. Cell phones use microwaves, which have wavelengths between 0.3 and 0.001 meters. Infrared waves come from (not so sure about this one) light bulbs and have wavelengths between 0.001 meters and 700 nanometers. Visible light (don't know exactly where it comes from, sorry) have wavelengths between 700 and 400 nanometers. Ultraviolet waves cause sunburn and have wavelengths between 400 and 10 nanometers. You should know where X rays come from and they have wavelengths between 10 and 0.01 nanometers. (Sorry for not including Gamma rays, I didn't have enough information on them). You can choose two of these seven and add the information if you want.
No. Your cellphone, many TV stations, and the GPS satellites transmit wavelengths shorter than 1 meter. X-rays have wavelengths between 0.00000000001 and 0.00000001 meter. (1/100th of a nanometer to 10 nanometers)

The ones we call "radio waves". That's the electromagnetic spectrum between maybe roughly speaking 10 KHz to 300 GHz., or wavelengths between 1 mm to 30 km.
Ultraviolet wave is a portion of the electromagnetic spectrum extending from the violet end of visible light to the X-ray region.Ultraviolet (UV) radiation lies between wavelengths of about 400 nanometres and 10 nanometres, corresponding to frequencies of 7.5 × 1014 Hz to 3 × 1016 Hz.

Radio, radio is around 10^3 m and visible light is around .5 *10^-6 m.
There is no longest wavelength. In the electromagnetic spectrum extremely low frequency waves can have wavelengths of less than 100 megametres (100,000 kilometres or 10^8 metres). Gravitational waves are likely to have much longer wavelengths.
EM waves with the shortest wavelengths are called gamma rays. The range of wavelengths that are called gamma rays is between 1 x 10^-12 meters and 1 x 10^-20 meters, or; .000000000001 m to .00000000000000000001 m .
Radio waves do not emit visible light. Only light with wavelengths of roughly 4*10^-7 to 7*10^-7 meters are visible.
The longest wavelength corresponds to long wave radio, I think the longest used is about 2000 meters. The shortest are gamma rays, which occur in radioactivity, these are from about 10-11 meters down.
Microwaves, defined as electromagnetic waves with wavelengths as long as 10 cm and as short as 0.1 cm, are not in the visible spectrum.
