The relationship between wave speed, wavelength and frequency can be written as,
Here, v is the wave speed, λ is the wavelength and f is the frequency of the wave.
The relationship connecting time period and frequency can be written as,
Here, T is the time period of the wave.
The relationship connecting time period and angular frequency can be written as,
Here, ω is the angular frequency.
The relationship connecting time period and frequency can be written as,
The relationship connecting wavenumber, wave speed and angular frequency can be written as,
Here, k is the wavenumber.
The direction of the velocities about the particles a, b, c, d and e is represented as arrows pointing in the direction of velocities in the figure below. It is denoted as v=0 at the points where the velocity is zero.
