Read each question carefully and provide your best answer. Show all your work for calculation problems.
1. Which of the following is NOT a characteristic of a mechanical wave?
Requires a medium for propagation
Transfers energy without transferring matter
Can travel through a vacuum
Exhibits reflection and refraction
2. The maximum displacement of a particle from its equilibrium position in an oscillation is called the:
Wavelength
Frequency
Amplitude
Period
3. A wave in which the particles of the medium oscillate perpendicular to the direction of wave propagation is called a wave.
4. The number of complete oscillations per unit time is known as the of the oscillation.
5. Explain the difference between a transverse wave and a longitudinal wave. Provide an example of each.
6. Analyze the wave diagram below and identify the following parts:
a) Crest:
b) Trough:
c) Wavelength:
d) Amplitude:
7. Sound waves are an example of transverse waves.
True
False
8. The period of an oscillation is inversely proportional to its frequency.
True
False
9. A wave has a frequency of 50 Hz and a wavelength of 3 meters. Calculate the speed of the wave.
10. A mass attached to a spring oscillates with a period of 0.8 seconds. What is the frequency of its oscillation?
