Wavelength is the distance between wave points. Wave velocity relates wavelength and frequency. Sound waves need a medium to propagate.
Wavelength: In physics, wavelength refers to the distance between two consecutive points on a wave that are in phase. It is measured in meters (m).
Relationship between wave velocity, wavelength, and frequency: Wave velocity = wavelength x frequency. As wavelength increases, frequency decreases proportionally to maintain a constant wave velocity.
Sound wave properties: Sound waves are mechanical waves that require a medium to travel, unlike light waves that can propagate through a vacuum.
