INFRARED WAVES

• Diffraction is when there is a hole or space.
• In 1800, William Herschel conducted an experiment measuring the difference in temperature between the colors in the visible spectrum. When he noticed an even warmer temperature measurement just beyond the red end of the spectrum, he had discovered infrared light.
• Infrared waves are given off by hot objects ( stars, lamps, flames and anything that are warm, like us ).
