The lower frequency waves are infrared, the higher ones are ultraviolet.
That would be sound waves, or the audio spectrum.
The radio band is the least energetic section of the electromagnetic spectrum.
Visible light is part of what is called the electromagnetic spectrum. Light is electromagnetic energy, and so are radio waves, microwaves, X-rays and gamma rays.
Visible light consists of the band of wavelengths to which the structure of the human eye is sensitive. Radiation outside of that band may enter the eye, but there's nothing in there that responds to it, so the brain remains unaware of it.
Humans are allowed to see a small portion of the electromagnetic spectrum known as visible light. This spectrum ranges from around 400 to 700 nanometers in wavelength and includes colors like red, orange, yellow, green, blue, indigo, and violet. Other waves in the electromagnetic spectrum such as infrared, ultraviolet, X-rays, and gamma rays are not visible to the human eye.
That's called visible light.
WiFi uses electromagnetic waves in the microwave band, around 2.4 GHz or 5 GHz.
The waves used to broadcast radio signals are called RF waves and these generally lie in VHF and UHF band of electromagnetic spectrum.
Infrared/ Ultravilote
The total of all electromagnetic waves is called the electromagnetic spectrum. The electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visible light waves, ultraviolet radiation, x-rays, and gamma rays. Only visible light waves, which humans see as the band of colors from red to violet, are the portion of the spectrum visible to the human eye, although many other life forms are sensitive to infrared and possibly to other segments the spectrum.
There are many types of waves covered by physics. Only electromagnetic waves in the visible light band have the property that we call "color".
That would be sound waves, or the audio spectrum.

the very low frequencies up through the AM radio broadcast band.
The radio band is the least energetic section of the electromagnetic spectrum.
RADAR = RAdio Detection And RangingRadio waves in the microwave band are used to measure the speed of cars using a technique called "Doppler RADAR", by measuring the change in frequency of the returned waves.These waves are electromagnetic waves.
