Unit 5 Assessment: Waves

Which of the following processes enables a cell phone to receive communications from a cell phone tower?

• Electromagnetic waves from the tower are reflected by the cell phone, producing an electromagnetic field that is detected by the internal circuits of the phone.

• Electromagnetic waves from the tower produce an electric current in the cell phone's internal circuit when intercepted by the phone's antenna.

• Electromagnetic waves diffract around the cell phone's antenna, which allows the waves to be detected by the internal circuits of the phone.

• Electromagnetic waves from the tower interfere with the radio waves emitted by the cell phone, producing electric currents in the internal circuits of the phone.

Which of the following best explains why different objects are different colors?

• Some objects perform photosynthesis while other objects do not.

• Some objects emit high-pressure light while other objects emit low-pressure light.

• Different objects reflect or emit light of different wavelengths.

• Different objects reflect or emit light of different speeds.

If you are attending a rock concert and the sound of the guitar is much louder than the singer’s voice, which of the following conclusions would be most reasonable?

• The singer is producing sound waves of a higher amplitude than the guitar’s strumming.

• The guitar is producing sound waves of a longer wavelength than the singer’s voice.

• The singer is producing sound waves of a longer wavelength than the guitar’s strumming.

• The guitar is producing sound waves of a higher amplitude than the singer’s voice.
