Below are sample questions representative of the exercises included on this worksheet and related 7.82 Waves Properties of Light and Sound skill assessments:

Problem 1Difficulty: Mastery
Which final model statement correctly connects amplitude, wavelength, energy, and frequency for waves in the same medium?
AEnergy and frequency can be found only by knowing the wave's color.
BLarger amplitude means lower wave energy; shorter wavelength means lower frequency.
CWavelength measures wave height; amplitude measures crest-to-crest distance.
DLarger amplitude means more wave energy; shorter wavelength means higher frequency.
Solution & Explanation:The skill focus is matching amplitude with wave energy and wavelength with frequency. In the same medium, a shorter wavelength corresponds to a higher frequency.
Problem 2Difficulty: Mastery
A wave model table gives these options in the same medium: Option A amplitude 7 cm, wavelength 9 cm; Option B amplitude 7 cm, wavelength 2 cm; Option C amplitude 2 cm, wavelength 9 cm; Option D amplitude 2 cm, wavelength 2 cm. Which option best represents high energy and low frequency?
AOption D
BOption C
COption A
DOption B
Solution & Explanation:High energy requires the larger amplitude of 7 cm. Low frequency requires the longer wavelength of 9 cm. The correct option has both.
Problem 3Difficulty: Mastery
A claim says Wave A has twice the frequency of Wave B, and both waves travel at the same speed. What must be true about Wave A's wavelength?
AIt is twice as long as Wave B's wavelength.
BIt cannot be compared to Wave B's wavelength.
CIt is the same as Wave B's wavelength.
DIt is half as long as Wave B's wavelength.
Solution & Explanation:At the same speed, frequency and wavelength are inversely related. Doubling frequency means wavelength becomes half as long.
