Which of the following devices is used to observe and study celestial objects across the universe?

• telescope

• microscope

• seismometer

• hygrometer

When you take a selfie with your cell phone, there is a sensor with pixels designed to detect red light, green light, and blue light. Together, these pixels can make up a full color image. What form of electromagnetic radiation is your cell phone camera design to detect?

• Visible Light

• Radio Waves

• X-rays

• Gamma Rays

NGSS.HS-PS4-4

Which of the following statements is true?

• There are machines and telescopes designed to explore space using every form of radiation from radio waves to gamma rays. This allows us to see much more of what's out in the universe.

• Telescopes can only use visible light. There are machines that explore space using radio waves and microwaves, but their use is limited.

• There are dedicated sonar devices used to measure and record sound energy in space. The sounds that travel through space can tell us a great deal about the properties of other stars.

• Telescopes can only observe space in a single wavelength (color) of visible light. Multiple telescopes are necessary to produce a full color image.

The speed of light (299,792 km/s) is...

• The speed that all forms of electromagnetic radiation travels, regardless of frequency or wavelength.

• The fastest speed possible for electromagnetic waves. Only the most energetic electromagnetic waves, like x-rays and gamma rays, can actually reach this speed.

• Equal to the speed of sound.

• too slow? Yes! We're gonna have to go right to... ludicrous speed!
