Electromagnetic radiation is very important to life on Earth. Not only do gases interact with electromagnetic radiation, but virtually all the energy on the Earth originates from electromagnetic radiation emitted by the Sun. Test your knowledge of electromagnetic radiation and the electromagnetic spectrum by answering the following questions. Use the Electromagnetic Spectrum Learning Tool as necessary.
What are the three parameters used to classify electromagnetic radiation? Provide a brief description of each.
- Wavelength. Wavelength is the distance between two identical points on adjacent oscillations along a wave.
- Frequency. Frequency is the number of events (often individual oscillations) that pass a fixed point in a specific unit of time.
- Energy. The energy of a wave is the ability of a wave to do work.
True or False: Wavelength and energy are directly proportional.
What form of electromagnetic radiation has the longest wavelength?
Approximately, what range of wavelengths does microwave radiation have?
What is the frequency of blue light? Of yellow light?
Hz to 
Hz. The frequency of yellow light is approximately 
Hz to 
Hz.
How much energy does a photon of red light have?
