How are Waves Transmitted? Quick Check
-
Question 1: What does it mean that a material transmits waves?
-
• Waves will pass through the material.
• Waves will strop and transfer energy when they hit the material.
• Waves will bend and change their direction slightly when they hit the material.
• Waves will bounce off the surface of the material.

Question 2: Science fiction movies sometimes take place in space and contain scenes where things explode very loudly and brightly. Why is this unrealistic?
-
• Matter is needed to transmit sound waves.
• The pressure in space would keep explosions from being very large.
• Large explosions are more likely to create seismic waves, not sound and light.
• Light waves cannot travel through the vacuum of space.

Question 3: Earthquakes can be recorded on a seismograph. This device produces a piece of paper with a long flat line, along with scribbles drawn with a needle that represent times when there has been an earthquake. How is energy transmitted to the seismograph?
-
• Sound waves carry energy through Earth and shake Earth below the seismograph.
• Seismic waves carry energy through Earth and shake Earth below the seismograph.
• Sound waves carry energy through the air and shake the needle of the seismograph.
• Seismic waves carry energy through the air and shake the needle of the seismograph.

Question 4: Which statement describes the transmission of mechanical waves?
-
• They can travel through matter, but not in a vacuum.
• They cannot travel through matter, but they can in a vacuum.
• They can travel through matter and in a vacuum.
• They cannot travel through matter not in a vacuum.
