wave A, and answer the following questions.
a.
b.
c.
d.
e.
Wave __________ has the same wavelength but smaller amplitude.
Wave __________ has a shorter wavelength but the same amplitude.
Wave __________ has a shorter wavelength and smaller amplitude.
Wave __________ has the same period and frequency.
Wave __________ and _________ have shorter periods and greater frequencies.
2. Determine the frequency of each wave. Count the number of crest in 1 second.
3. Use a ruler to determine the wavelength of each wave. Measure in centimeters.
Problems on Wave Velocity
1. If the frequency is 2 Hz and the wavelength is 0.5 meter. What is the speed of the wave?
2. If the wavelength is 2 m and the frequency is .1 Hz then, what is the speed of the wave?
3. What is the wavelength of a wave when the speed is 300 m/s and the frequency is 4 Hz?
4. What is the frequency of a wave when the speed is 1000 m/s and the wavelength is 0.4 m?
5. How fast is a wave moving if its wavelength is 10 m and its frequency is 440 Hz?
6. Waves pass the end of a dock 2 times every second. If the waves are 3 meters long, how fast are they
moving?
7. Waves that are 4 meters long move past a lighthouse with a speed of 1 m/s. What is the frequency of the
wave motion?
8. If you stand at the end of a pier and 10 waves pass by in 4 seconds. What is the wave frequency?
9. A sound wave with a wavelength of .5 meters has a frequency of 680 Hz. What is the speed of the
sound wave?
10. A wave is moving toward shore with a velocity of 5.0 m/s. If the frequency is 2.5 Hz, what is the
wavelength?
