Electromagnetic Spectrum Test Review

Astronomers use different types of telescopes to observe different parts of the electromagnetic spectrum. This allows astronomers to study objects in space. Some electromagnetic waves are blocked by Earth’s atmosphere, making it difficult for astronomers to focus the energy into a viewable image. Instead of actually viewing the energy, astronomers have learned to view the interactions of the energy with the atmosphere. These faint interactions with the atmosphere allow them to study highly energetic objects such as pulsars and black holes.

If the waves that are being observed have a frequency of 10²², what type of wave is being observed?

• Gamma

• UV

• Radio

• Xray

Look at the diagram of a liquid heated with microwaves.

 

How do microwaves interact with matter and generate heat?

• Microwaves reflect off the surface of matter which causes it to heat up.

  
  

• Microwaves are high-energy waves that transfer this energy into matter and break down atoms to create heat.

  
  

• Microwaves are heat waves that transfer through matter.

  
  

• Microwaves cause the particles in objects to move faster, thus increasing the heat of the object.
