Waves: Forces and Motion

This chart compares three different types of waves.  How do the wave characteristics compare for these waves?

• Sound waves and P-waves are longitudinal waves, while light waves are transverse waves
• Light waves and P-waves are transverse waves, while sound waves are longitudinal waves
• Sound waves, P-waves, and light waves are all longitudinal waves
• Light waves, P-waves, and sound waves are all transverse waves

How does sound usually travel?

• An object vibrates, and those vibrations travel through the air in one direction as transverse waves
• An object vibrates, and those vibrations carry air in one direction as longitudinal waves
• An object vibrates, and those vibrations carry air in all directions as transverse waves
• An object vibrates, and those vibrations travel through the air in all directions as longitudinal waves

This is a wave pattern diagram for two transverse waves.  How do the waves compare?

• Both waves have the same frequency
• Both waves have the same wavelength
• Wave 1 has a longer wavelength than Wave 2
• Wave 1 has a higher frequency than Wave 2

Why does sound travel faster through a solid object than in the air?

• The atoms in the solid object are farther apart than the atoms in the air
• The atoms in the solid object are closer together than the atoms in the air
• The atoms are smaller in the solid object than the atoms in the air. 
• The atoms are larger in the solid object than the atoms in the air

How are earthquakes, sound, and light waves alike?

• They transmit energy
• They carry matter
• They travel in space
• They can be seen

What is the relationship between eyesight and light?

• Light shines on all objects, allowing people to see them
• Light shines through all objects, allowing people to see them. 
• Light enters the eye before striking an object, allowing people to see the object. 
• Light reflects off an object and then enters the eye, allowing people to see the object

Which best explains the relationship between the electromagnetic spectrum and sight?

• Visible light is the part of the electromagnetic spectrum that can be seen with the eye.
• Ultraviolet light is the part of the electromagnetic spectrum that can be seen with the eye. 
• Visible light and infrared light are the parts of the electromagnetic spectrum that can be seen with the eye. 
• Ultraviolet light and infrared light are the parts of the electromagnetic spectrum that can be seen with the eye

Which best explains the relationship between the speed of sound and the medium through which it passes?

• Sound travels faster in solids because of the increased distance between solid particles.
• Sound travels faster in air because of the decreased distance between air particles. 
• Sound travels slower in air because of the increased distance between air particles. 
• Sound travels slower in solids because of the decreased distance between solid particles.

Josephine adds thicker strings to her guitar.  What does that do?

• It prevents the guitar from using air particles to transfer the sound.
• It changes the number of strings on the guitar
• It changes the vibrations made by the guitar
• It prevents the guitar from making sounds
