Unit 5: Waves

What kind of wave is pictured?

• transverse

• longitudinal

Answer explanation

The wave depicted is transverse because the oscillations occur perpendicular to the direction of wave travel, unlike longitudinal waves where oscillations are parallel. This characteristic confirms it as a transverse wave.

What is letter B pointing to?

Answer explanation

Letter B is pointing to the crest, which is the correct answer. The crest typically refers to the top or highest point of something, making it the appropriate choice in this context.

What is amplitude a measure of?

Answer explanation

Amplitude measures the maximum extent of a wave's oscillation, which is directly related to the energy carried by the wave. Therefore, the correct answer is 'energy'.

How would you measure the amplitude of this kind of wave?

Answer explanation

To measure the amplitude of a wave, you determine the height from the resting point (equilibrium) to the crest (highest point). This measurement reflects the wave's maximum displacement from its rest position.

What kind of wave is pictured?

• transverse

• longitudinal

Answer explanation

The wave depicted is longitudinal, where the particle displacement is parallel to the direction of wave propagation, unlike transverse waves where displacement is perpendicular.

What is letter A pointing to?

Answer explanation

Letter A is pointing to the area of rarefaction, which is characterized by a decrease in pressure and density in a wave. This is the correct answer as it directly relates to the concept being asked.

What is letter B pointing to?

Answer explanation

Letter B is pointing to the wavelength, which is the correct answer. It indicates the distance between successive peaks of a wave.
