Question on: SS1 Physics - Sound And Waves

 Wavelength is the distance between two consecutive points in a wave that are in phase. It is typically measured as the distance between two identical points on adjacent wave cycles, such as from crest to crest or trough to trough. Wavelength is denoted by the symbol λ (lambda) and is measured in metres (m) or any other appropriate unit of length.

   Period refers to the time it takes for one complete cycle of a wave to pass a given point. It is the reciprocal of the frequency of the wave. Period is denoted by the symbol T and is measured in seconds (s) or any other appropriate unit of time.

   Speed of a wave refers to the rate at which the wave propagates through a medium. It represents the distance travelled by a wave per unit of time. Speed is denoted by the symbol v and is measured in metres per second (m/s) or any other appropriate unit of velocity.
