We would call any wave longer than 1 millimeter a "radio wave".
100 meters and longer would be 3mhz and lower. Divide the speed of light ( C=3.0*10^8 meters per second) by the wavelength. You get frequency.
When you pluck the wire Longitudinal waves are produced.
for wavelength, the longer of the two is visible light, but the longest type of rays are radio waves (some of them have a wavelength as long as a football field)
Waves of extremely short wavelength produced as a result of transitions of electrons in an atom.
Radio waves are electromagnetic waves and are a part of the electromagnetic spectrum. Other electromagnetic waves in the electromagnetic spectrum are microwaves, visible light, infrared, ultraviolet, x-rays, and gamma rays
Radio waves have the longest wavelengths.
long wavelengths and low frequency...? Not sure what kind of answer you're looking for here.
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.
The symbol for wavelength is the lower case Greek letter lambda - which looks like an upside-down y. The unit of measurement depends on the kind of wave: electromagnetic waves, for example, have wavelengths ranging from 10^-11 metres (10 picometres) to 1 kilometre. Other waves can have even longer wavelengths.
That depends on what kind of wave you are talking about. In the case of electromagnetic waves, the smaller wavelengths indeed represent more energetic radiation.

Wavelengths
Hertz is a measurement of wavelength. It is the number of cycles in a second. You can also measure wavelength by the length of the wave moving at the speed of light. 3.5 MHZ (Mega Hertz) is about 80 meters long.
They are transverse waves.
What kind of electromagnetic waves does the sun have?
The equipment will depend on the kind of waves. Electromagnetic waves, for example, have wavelengths ranging from 10^-11 metres to 10^3 metres. Clearly, the equipment to measure something as long as 1 kilometre will be different from that used to measure something shorter than a billionth of a metre.
They are tranverse waves.
