define the terms frequency wvelength and velocity of a sound wave what is the relation between them

 Frequency : The no of complete oscillations per unit time is called frequency. It is also known as reciprcal of time period. It is represented by latin letter neu

Wavelength : The distance between two consecutive crests or two consecutive trough is the wavelength of a wave. It is represented by latin letter lambda

Velocity : It is the distance. Travelled by a wave per unit ti.e. Its. SI unit isms^-1
