Some planetary images and satellite photographs are made using visible light.  Other images are made with radiation from the non-visible portions of the electromagnetic spectrum.  Why do scientists study images made with parts of the electromagnetic spectrum other than visible light?

 

 

• These images are the only way to observe galaxies beyond our own

• These images reveal information that visible light does not show

• These images show important data from optical telescopes

• These images are the only way to observe space from Earth’s surface

Sunscreen bottles often include the phrase: “Protects against UVA and UVB waves.” This refers to ultraviolet radiation coming from the sun. Which of the following is true of ultraviolet radiation?

• Ultraviolet radiation has shorter wavelengths than x-rays, therefore it is more dangerous than xrays.

• Ultraviolet radiation has longer wavelengths than infrared light, therefore it is more dangerous than infrared light.

• Ultraviolet radiation has shorter wavelengths than visible light, therefore it is more dangerous than visible light.

• Ultraviolet radiation has longer wavelengths than gamma radiation, therefore it is more dangerous than gamma radiation.

• Infrared

• Gamma Rays

• Radio Waves
