7SCI-Q1-T4- Lesson 7.2 Wave Properties:

What is the amplitude of a transverse wave?

• The distance from crest to crest

• The maximum displacement from the midpoint to the crest or trough

• The distance from compression to compression

• The speed of the wave

How does the amplitude of a wave relate to the energy it carries?

• Energy is inversely proportional to the amplitude

• Energy is directly proportional to the amplitude

• Energy is directly proportional to the square of the amplitude

• Energy is not related to amplitude

In a longitudinal wave, what does increased amplitude indicate?

• More energy transfer due to increased compression and rarefaction

• Less energy transfer due to decreased compression and rarefaction

• No change in energy transfer

• A decrease in wave speed

What is the wavelength of a wave?

• The time it takes for one complete wave to pass a point

• The distance between consecutive points in phase, such as crest to crest

• The height of the wave from the midpoint to the crest

• The speed of the wave

Which of the following correctly describes the relationship between amplitude and energy in transverse waves?

• Higher amplitude means less energy

• Higher amplitude means more energy

• Amplitude does not affect energy

• Amplitude is inversely proportional to energy

In a longitudinal wave, what does the term "compression" refer to?

• The point where the wave is at its highest

• The point where particles are closest together

• The point where particles are farthest apart

• The midpoint of the wave

• From midpoint to crest

What happens to the energy of a wave if its amplitude is doubled?

• The energy remains the same

• The energy is doubled

• The energy is quadrupled

• The energy is halved

In transverse waves, what is the term for the highest point of the wave?

• Trough

• Crest

• Compression

• Rarefaction

What is the effect of increased amplitude on the medium in a longitudinal wave?

• The medium becomes less compressed and rarefied

• The medium becomes more compressed and rarefied

• The medium's speed increases

• The medium's speed decreases
