• It is absorbed by the atmosphere

• It is outside the visible spectrum

• It is too dim

What technology is used to detect infrared energy?

• Spectrometers

• Special cameras

• Telescopes

• Microscopes

What do special cameras do with the infrared energy they detect?

• Convert it into a viewable image

• Convert it into sound

• Store it for later use

• Reflect it back

Which of the following is NOT a function of special cameras in the context of infrared?

• Detecting infrared energy
