Key Points - Sunlight and the Electromagnetic Spectrum

• The sun’s energy arrives as radiation with a wide range of wavelengths, including infrared, visible, and ultraviolet.
• White light is made up of a spectrum of many different colors.
• Light waves with a long wavelength have a low frequency and waves with a short wavelength have a high frequency.
• The speed of light is equal to the wavelength multiplied by the frequency of any light wave.
• There are many applications of the electromagnetic spectrum including medical and satellite imagery.
