Step-by-step explanation:
Wavelength :
The distance travelled by a wave between is called the wavelength of a wave. It is basically defined as the distance between two consecutive crests or troughs. The crest is the maximum distance traveled by the wave and the trough is the minimum distance traveled by the wave.
Frequency :
The number of oscillation or vibration per second is called the frequency of a wave. It is also defined as the reciprocal of time period.
Also, there is a relationship between the wavelength and the frequency of a wave as :
![v=\\u * \lambda](https://img.qammunity.org/2020/formulas/physics/college/ty5qs5kayzjb0wong6ejxetyhhjlnffq32.png)
is the frequency
is the wavelength
