# Find wave speed given frequency and wavelength relationship

### Wavelength and the Index of Refraction

Frequency period formula angular frequency cycle per second hertz Hz amplitude equation formulary acoustic time wavelength Hz and frequency f to cycle duration or period T ○ T = 1 / f and f = 1 / T . If the graph shows at the x axis the distance d, we see the wavelength λ. From both together, the wave speed can be. From the above formula, we can find the Unit of Wavelength. v = Phase speed or speed of the wave measured in m/s, f = frequency of the wave measured in. Example. Calculate the time period of a wave with a frequency of 50 Hz. T = \frac{ 1}{f} The speed of a wave can be calculated using the equation: wave speed.
