Microwaves are used in radar, in communications, and for heating in microwave ovens and in various industrial processes.]]> 2017-03-02 20:56:08 UTC https://padlet.com/anriquee_johnson/x07us4mf0pfn/wish/157482249 infrared waves anriquee_johnson https://padlet.com/anriquee_johnson/x07us4mf0pfn/wish/157482385 having a wavelength just greater than that of the red end of the visible light spectrum but less than that of microwaves. Infrared radiation has a wavelength from about 800 nm to 1 mm, and is emitted particularly by heated objects.]]> 2017-03-02 20:56:42 UTC https://padlet.com/anriquee_johnson/x07us4mf0pfn/wish/157482385 VISIBLE waves anriquee_johnson https://padlet.com/anriquee_johnson/x07us4mf0pfn/wish/157482696
Visible light is a form of electromagnetic (EM) radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. Generally,visible light is defined as the wavelengths that arevisible to most human eyes. ... This broad range of wavelengths is known as the electromagnetic
