Infrared (IR) is invisible radiant energy, electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 700 nanometers (frequency 430 THz) to 1 mm (300 GHz) (although people can see infrared up to at least 1050 nm in experiments).
If the statement is true, write âTâ on the line in front of the statement. If it is false, write âFâ and rewrite the statement to make it true. 13) Radiant energy spreads out from its source in all directions. 14) Electromagnetic radiation includes only visible light waves. 15) Microwaves are a type of infrared wave. 16) X rays have more energy than gamma rays. 17) Radio waves, microwaves and ultraviolet waves all have longer wavelengths than visible light. 18) Both X rays and gamma rays have higher frequencies than ultraviolet rays. 19) The Sun radiates both visible energy and invisible energy. 20) Communicating with satellites is an application of gamma rays.
