Electromagnetic waves have many common applications. Which of the following options matches a type of electromagnetic radiation with a common application?

• Microwaves and tanning beds

• Radio waves and water purification

• Infrared waves and thermal imaging

• Ultraviolet waves and weather radar

The figure to the left shows different images of the Crab Nebula but with different wavelengths of the EM spectrum.  Why do scientists use different wavelengths of light to capture images?

• Each wavelength provides the same information.

• Each wavelength is unique and can provide its own specific information on the object.

• Each wavelength can be used for specific types of objects that can’t be detected by other wavelengths.

• Each wavelength is the same, but can provide different information.

Which statement is accurate about the types of electromagnetic radiation?

• Each type is visible to humans.

• Each type has the same energy.

• Each type has different wavelengths.

• Each type has the same frequencies.
