Radio radiation : 
Radio waves are a type of electromagnetic radiation, as are microwaves, infrared radiation, X-rays and gamma-rays. The best-known use of radio waves is for communication; television, cellphones and radios all receive radio waves and convert them to mechanical vibrations in the speaker to create sound waves that can be heard.

Ultraviolet radiation : designates a band of the electromagnetic spectrum with wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays.                                                    https://en.wikipedia.org/wiki/Ultraviolet]]> 2019-01-28 19:25:32 UTC https://padlet.com/334085/ic6bjoqmq2vv/wish/325114943 334085 https://padlet.com/334085/ic6bjoqmq2vv/wish/325118557 11. Visible light radiation : Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to 740 nanometers.                                                                                                                                                         https://en.wikipedia.org/wiki/Visible_spectrum]]> 2019-01-28 19:32:07 UTC https://padlet.com/334085/ic6bjoqmq2vv/wish/325118557 334085 https://padlet.com/334085/ic6bjoqmq2vv/wish/325139766 12.
