Wave Characteristics
Wave characteristics are measurable features of a wave, mainly wavelength, frequency, time period, and amplitude.
Practice This ConceptMain explanation
Teacher explanation
Wavelength is the distance between two consecutive compressions or two consecutive rarefactions. Frequency is the number of vibrations per second, measured in hertz. Time period is the time for one complete vibration. Amplitude is the maximum displacement from the mean position and is linked with loudness.
Example
If a tuning fork vibrates 256 times in one second, its frequency is 256 Hz and its time period is 1/256 s.
Simple analogy
Frequency counts how often; time period tells how long for one.
Common confusion
Students often confuse frequency with amplitude. Frequency affects pitch, while amplitude affects loudness.
Exam tip
Write units carefully: wavelength in metre, frequency in hertz, time period in second, and amplitude in metre.
Study the wave characteristics diagram carefully
