Question

which feature of a wave can be calculated using the formula below? number of wavelengths / time wavelength speed frequency amplitude

Explanation:

The frequency of a wave is defined as the number of wavelengths that pass a given point per unit time. The formula "number of wavelengths / time" represents frequency. Wavelength is the distance between two - consecutive points in phase on a wave. Speed is the product of wavelength and frequency. Amplitude is the maximum displacement of a wave from its equilibrium position.

Answer:

C. frequency
