U2.6 Checkpoint #2

The distance between two corresponding parts of a wave is its

• trough

• frequency

• wavelength

• amplitude

The less energy a wave has, the smaller its

• crest

• frequency

• wavelength

• amplitude

How often a wave occurs is the wave’s

• crest

• frequency

• wavelength

• amplitude

Frequency is measured in units called

• periods

• nanoseconds

• hertz

• eras

All waves have wavelength, frequency, amplitude, and speed.

• true

• false

The ​ (a)   of a wave remains constant if the medium, temperature, and pressure do not change.

• speed
• frequency

The height of a wave’s wavelength depends on its amplitude.

• true

• false

The amplitude of a(n) transverse wave is a measure of how compressed or rarefied the medium becomes.

• true

• false

Dividing the distance a wave travels by the time it takes to travel that distance gives you the wave’s speed.

• true

• false

Organize these options into the right categories

Groups:

(a) Transverse Waves

,

(b) Longitudinal Waves

• Medium vibrates perpendicular to the direction of motion.

• Amplitude depends on the density of compressions.

• Medium vibrates parallel to the direction of motion.

• Wavelength measured from beginning of one compression to the beginning of the next compression.

• Wavelength measured from crest to crest.

• Amplitude measured from rest position to crest or trough.
