We use it for sound, Radio,TV, RADAR, Cell Phones, Heat, Tanning, X-Rays, Medicine, Nuclear Bombs, etc, etc,etc.

The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
Digital Versatile Disc (DVD) uses 650nm wavelength laser diode light (part of the electromagnetic spectrum, in visable light section) which allows us to see it. CD uses 780nm wavelength, just outside of the electromagnetic spectrum, hence why we cannot 'see' it, only hear.
Quite simply, the Microwave Oven uses the Microwave part of the spectrum.
we use electromagnetic waves in radios and cell phones

It is not at all clear what you mean by locating the electromagnetic spectrum. Electromagnetism exists at innumerable locations throughout the universe. Vision is a sense that uses a part of the electromagnetic spectrum, and lots of animals can see. Some animals, such as bees, can see in ultraviolet frequencies that the human eye does not see.
Anything that can reflect light is only visible to an eye... others which cannot are dark..
It uses radio waves between the range of 2.402 and 2.480 GHz
Quite simply, the Microwave Oven uses the Microwave part of the spectrum.
electromagnetic radiation in the microwave range some times cell phones use 50% uses and 50%health prombles overtimes don t uses
An OttLite actually uses full spectrum lighting, so there is no difference. Full spectrum means the light simulates natural sunlight, and that covers the electromagnetic spectrum from infrared through near-ultraviolet, or all wavelengths that are useful to plant or animal life.
To answer the question which of these is electronic protection activity there needs to be a choice. Electronic protection activity is any action that uses direct energy or electromagnetic spectrum.
An electromagnetic flow meter is a flowmeter which uses the electromagnetic technology to determine the amount of volume flow though a pipe. View the Related Links section for a link with a video about this.
