Write the letter of the correct location next to its matching vocabulary term

• rest position

• E

• trough

• B

• crest

• C

• amplitude

• D

• wavelength

• A

The vertical distance between a peak or valley and the resting position in a transverse wave is called a(n)

• crest

• trough

• amplitude

• wavelength

As a wavelength increases in size, its energy

• increases

• decreases

• stays the same

• changes unpredictably

The distance from one compression to the next in a longitudinal wave is called a(n)

• crest

• trough

• aplitude

• wavelength

Waves are generated when a source of ______ forces the matter in a medium to vibrate.

• amplitude

• energy

• rarefaction

• vibration

Waves that move through a medium at right angles to the direction of the wave are called_____.

• mechanical

• transverse

• longitudinal

• trough

Which student is correct?

Kayleigh: Wave 1 has the most energy because it has the greatest wavelength.

Tucker: Wave 2 has the most energy because it has a higher frequency.

• Kayleigh

• Tucker

• neither student

• both students

Which evidence supports the answer to Part A?

Kayleigh: Wave 1 has the most energy because it has the greatest wavelength.

Tucker: Wave 2 has the most energy because it has a higher frequency.

• 1. The longer the wavelength, the higher the energy in a wave.

• 1. The higher the frequency, the higher the energy in a wave.

• The amount of energy in a wave does not impact the frequency.

• The amount of energy in a wave does not impact the wavelength.

A wave in the ocean has a wavelength of 2 m and a frequency of 0.5 Hz. What is the speed of this wave?

• 10 m/s

• 1 m/s

• 0.1 mi/hr

• 10 m

Suppose you knew the speed and frequency of a wave. What property of the wave would you be able to calculate? What would that formula look like?

• Calculate for Wavelength.
  W = S ÷ F

• Calculate for Wavelength.
  W = F ÷ S

• Calculate for Speed.
  S = W x F

• Calculate for Wavelength.
  S = W ÷ F
