We use microwaves to cook food, transmit information, and in radar that helps to predict the weather. Microwaves are useful in communication because they can penetrate clouds, smoke, and light rain. The universe is filled with cosmic microwave background radiation that scientists believe are clues to the origin of the universe they call the Big Bang. ]]> 2016-12-19 17:36:55 UTC https://padlet.com/12161761/5t9i9hx0bdr2/wish/144355884 12161761 https://padlet.com/12161761/5t9i9hx0bdr2/wish/144356079 Between microwaves and visible light are infrared waves. Infrared waves are sometimes classified as "near" infrared and "far" infrared. Near infrared waves are the waves that are closer to visible light in wavelength. These are the infrared waves that are used in your TV remote to change channels. Far infrared waves are further away from visible light in wavelength. Far infrared waves are thermal and give off heat. Anything that gives off heat radiates infrared waves. This includes the human body.]]> 2016-12-19 17:37:54 UTC https://padlet.com/12161761/5t9i9hx0bdr2/wish/144356079 12161761 https://padlet.com/12161761/5t9i9hx0bdr2/wish/144356294 The visible light spectrum covers the wavelengths that can be seen by the human eye. This is the range of wavelengths from 390 to 700 nm which corresponds to the frequencies 430-790 THz.
