How is energy transferred through a longitudinal wave?

• Energy is transferred by the heat generated in the medium.
• Energy is transferred only through the movement of waves in water.
• Energy is transferred through the vibration of the medium's surface.
• The disturbance causing the wave is in the same direction as the transfer of energy through the medium.

How is energy transferred through a transverse wave?

• Energy is transferred by the movement of particles in a circular motion in a transverse wave.
• The disturbance causing the wave is perpendicular to the transfer of energy through the medium.

• Energy is transferred by the parallel motion of particles in a transverse wave.
• Energy is transferred through compression and rarefaction in a transverse wave.

Identify each correct statement about transverse waves.

• 1. Transverse waves are not mechanical waves.

• The medium vibrates perpendicular to the flow of energy in a transverse wave.

• Transverse waves do not have wavelengths.

Identify a real-life example of a longitudinal wave

• Seismic P-waves in the Earth
• Light waves in a vacuum
• Sound waves in air
• Water waves in the ocean

Identify a real-life example of a transverse wave

• Sound waves in air
• Waves on a string (e.g., shaking a rope)
• Water waves in the ocean

What is a wave?

• A wave is a fixed position in space that does not change.
• A wave is a solid object that cannot move.
• A wave is a type of particle that exists in a vacuum.
• A wave is a disturbance that transfers energy through space or matter.
