The time period of a wave is defined as:
The distance between two consecutive crests
The number of complete wave cycles passing a point per unit time
The time taken for one complete wave cycle
The maximum displacement of a particle from its equilibrium position

The relationship between wavelength, frequency, and speed of a wave is not correct?
Wavelength = Speed / Frequency
Frequency = Speed / Wavelength
Speed = Wavelength / Frequency
Speed = Frequency x Wavelength
