In a crowded concert, the way sound travels from the stage to the audience is most similar to which type of wave motion?

• A wave where particles move in a circular motion.

• A wave where particles move parallel to the direction of the wave.

• A wave where particles move perpendicular to the direction of the wave.

• A wave where particles move in the opposite direction of the wave.

When observing waves at the beach, unlike the up and down motion of a cork floating on the water (a longitudinal wave), the disturbance in a wave hitting the shore (a transverse wave) is

• perpendicular to the direction the wave travels.

• in a circular motion.

• parallel to the direction the wave travels.

• in the opposite direction of the wave's travel.

While observing the waves created by a tuning fork in a physics lab, a student wonders: What type of wave is this?

• Electromagnetic

• Mechanical

• Both Electromagnetic and Mechanical

When a wave is travelling through the ocean, what happens to the water particles?

• The water particles are pulled along behind the wave as that makes it a longitudinal wave.

• The wave is making the water particles move back and forth as that will make a transverse wave.

• The wave is making the water particles move up and down.

• The water particles are pulled along behind the wave as that makes it a compressional wave.

• The water particles do not move along with the wave.

During a concert, how does the sound from the instruments reach the audience?

• Through the air as a medium.

• Sound is unrelated to the vibrations of the instruments.

• Sound cannot travel through the concert hall's atmosphere.

• Sound can travel even in the vacuum of space.
