The speed of a transverse wave on a stretched string may be altered by changing the tension in the string. A stationary wave pattern is produced on a stretched string by an oscillator operating at a frequency of $650\,\text{Hz}$. What change must be made to the wave so that the same stationary wave pattern is kept when the applied frequency is raised to $750\,\text{Hz}$?
- ADecrease the speed of the wave on the string.
- BDecrease the wavelength of the wave on the string.
- CIncrease the speed of the wave on the string.
- DIncrease the wavelength of the wave on the string.
