In sound waves, wavelength is the distance between two consecutive compressions or rarefactions. Frequency is the number of oscillations per second, measured in Hertz. Time period is the time taken for one complete oscillation, measured in seconds. Amplitude is the maximum displacement from the mean position, also measured in meters.
Here’s a more detailed breakdown:
Wavelength (λ):
This represents the distance a sound wave travels during one complete cycle of vibration. It’s often measured from crest to crest or trough to trough.
Frequency (f):
This refers to how many complete sound wave cycles occur in one second. It’s what determines the pitch of a sound, with higher frequencies sounding higher and lower frequencies sounding lower.
Time Period (T):
This is the time it takes for one complete cycle of the sound wave to pass a specific point. It’s the inverse of the frequency.
Amplitude (A):
This is the measure of the maximum displacement of the sound wave’s particles from their resting position. It’s related to the loudness or intensity of the sound, with larger amplitudes resulting in louder sounds.
