Which equation correctly expresses the frequency of a wave in terms of its speed and wavelength?
frequency=speed×wavelength\text{frequency} = \text{speed} \times \text{wavelength}frequency=speed×wavelength
frequency=speedwavelength\text{frequency} = \frac{\text{speed}}{\text{wavelength}}frequency=wavelengthspeed
frequency=wavelengthspeed\text{frequency} = \frac{\text{wavelength}}{\text{speed}}frequency=speedwavelength
frequency=1speed×wavelength\text{frequency} = \frac{1}{\text{speed} \times \text{wavelength}}frequency=speed×wavelength1
