1. A periodic wave with wavelength of 8 m has wave speed of 5 m/s. What is the wave's frequency?
2. A periodic wave with frequency of 4 Hz has speed of 20 m/s. What is the wave's wavelength.
3. A periodic wave with wavelength of 2 m has a frequency of 4 Hz.

Answer:
The formula for frequency is: f (frequency) = 1 / T (period). f = c / λ = wave speed c (m/s) / wavelength λ (m). The formula for time is: T (period) = 1 / f (frequency). λ = c / f = wave speed c (m/s) / frequency f (Hz).
