What effect does increasing the tension in a string have on the frequency of the stationary wave produced?.
- A.Increases the frequency
- B.Decreases the frequency
- C.No effect on frequency
- D.Increases the wavelength
Model answer
What a good answer should say
- Increases the frequency
Explanation
Why this works
Increasing the tension in a string increases the speed of the wave, which in turn increases the frequency, as frequency is directly proportional to wave speed.
