Wavelength - The wavelength is defined as the linear distance between two consecutive particles which are exactly at the same phase of motion.

Frequency - The number of complete oscillations made by a wave particle in one second is called the frequency of wave.

Time period - The time taken for a wave particle to make one complete oscillation is called time period of the wave.

Amplitude - The maximum displacement of a wave particle from the rest position is called the amplitude of the wave.
