No, light is not part of the radio spectrum. But, both the radio spectrum and light are part of the electromagnetic spectrum. The electromagnetic spectrum is a range of frequencies from very low to very high. Light frequencies are higher than radio frequencies but both are the same kind of thing.
bluetooth is an open wireless protocol for exchanging data over short distances. it uses short length radio frequencies. bluetooth uses a radio technology called frequency-hoping spread spectrum.
Radio waves are the longest of the E-M spectrum. The VLF (very low frequency) part of the radio spectrum is the longest usable part of that spectrum. This goes down to about 10kHz, and these low frequencies are used to communicate with submerged submarines.
The Midland brand of 2 way radios operate on the Family Radio Service channels (FRS) section of the radio spectrum. These bands of the radio spectrum are open for use by anyone and do not require permission from the authorities to use. Each radio operates as a radio transmitter and a radio reciever.
Many people have been linked with the discovery of the radio. Technically the first radio to be transmitted through electromagnetic waves was in 1980. Many others have since developed the strength and efficiency of the commonly known radio.

Spelling difference.... :)

A spectrum.
The spread spectrum technique is supposed to be less susceptible to natural noise, co-channel RF interference, intentional jamming, and unauthorized eavesdropping. It should also be less susceptible to degradation due to multipath fading, which is highly frequency-selective.

It is electromagnetic radiation in the radio par of the spectrum.
