Understanding Waves and Energy Transfer

What is the role of a medium in wave propagation?

• It moves along with the wave.

• It absorbs the energy of the wave.

• It amplifies the wave's energy.

• It transfers energy without moving itself.

In the example of a wave pool, what primarily acts as the medium?

• The pool walls

• The water in the pool

• The people in the pool

• The air above the pool

How does a transverse wave move in relation to its direction of travel?

• Parallel to the direction of travel

• Perpendicular to the direction of travel

• In a circular motion

• In a zigzag pattern

What is the equilibrium line in a wave?

• The lowest point of the wave

• The point where the wave starts

• The highest point of the wave

• The resting position of the medium

What is the relationship between energy and amplitude in a wave?

• Amplitude decreases as energy increases

• Energy and amplitude are unrelated

• More energy results in a smaller amplitude

• More energy results in a larger amplitude

How can the wavelength of a transverse wave be measured?

• All of the above

• From node to node

• From trough to trough

• From crest to crest

What is a longitudinal wave also known as?

• A surface wave

• A compressional wave

• A transverse wave

• A torsional wave

In a longitudinal wave, what is a compression?

• A region where particles are furthest apart

• A region where particles are closest together

• A point where the wave stops

• A point where the wave changes direction

What is a rarefaction in a longitudinal wave?

• A point where the wave is at its lowest

• A point where the wave is at its highest

• A region where particles are closest together

• A region where particles are furthest apart

How is the wavelength of a longitudinal wave measured?

• Both B and C

• From rarefaction to rarefaction

• From crest to crest

• From compression to compression
