A vibration generator sends waves through a gel pad. At setting 1, the wavelength is 1.2 cm. At setting 2, the wavelength is 0.0080 m. The wave speed in the gel remains constant.
Which statement gives the change in frequency from setting 1 to setting 2?
The frequency increases to 1.51.51.5 times its value at setting 1.
The frequency increases to 150150150 times its value at setting 1.
The frequency decreases to 1150\dfrac{1}{150}1501 of its value at setting 1.
The frequency decreases to 23\dfrac{2}{3}32 of its value at setting 1.
