- 16.
A wave travels at 15m/s and the crests are 5 meters apart. How many waves would you see pass by you per second?
- A.
15 Hz
- B.
5 Hz
- C.
45 Hz
- D.
3 Hz
Correct Answer
D. 3 HzExplanation
frequency = velocity divided by the wavelength. so you would take 15/5 = 3 hertzRate this question:
-
- 17.
Calculate the wave speed of a wave that has a frequency of 4 hz and a wavelength of 8 meters.
- A.
24 m/s
- B.
2 m/s
- C.
32 m/s
- D.
4 m/s
Correct Answer
C. 32 m/sExplanation
Using the wave speed formula: v = wavelength x frequency. You would mulitply 4 x 8 = 32 m/sRate this question:
-
- 18.
What is the wavelength of a wave with a speed of 50 m/s and a frequency of 5 hz.
- A.
5 meters
- B.
15 meters
- C.
250 meters
- D.
10 meters
Correct Answer
D. 10 metersExplanation
wavelength = velocity divided by frequency which would be 50/5 which would give you 10meters.Rate this question:
