1. In a transverse wave, how do the oscillations relate to the direction of energy transfer?
- A. A. Parallel to it
- B. B. Perpendicular to it
- C. C. Opposite to it
- D. D. There is no relationship
2. Which of the following is an example of a longitudinal wave?
- A. A. Light
- B. B. Water ripples
- C. C. Sound
- D. D. Radio waves
3. A wave has a frequency of 10 Hz and a wavelength of 3 m. What is its speed?
- A. A. 3.3 m/s
- B. B. 13 m/s
- C. C. 30 m/s
- D. D. 0.3 m/s
4. As a sound wave travels through air, what happens to the air particles?
- A. A. They travel along with the wave to its destination
- B. B. They oscillate about a fixed position while the wave transfers energy
- C. C. They are destroyed and recreated at the next position
- D. D. They move only in the direction opposite to the wave
5. A wave has a period of 0.02 s. What is its frequency, and does this tell you its wavelength without more information?
- A. A. 50 Hz; yes, wavelength can be found from frequency alone
- B. B. 0.02 Hz; yes, wavelength can be found from frequency alone
- C. C. 50 Hz; no, wavelength also requires knowing the wave speed
- D. D. 20 Hz; no, wavelength cannot ever be calculated
