What are the properties of waves?
Physics
ScanSolve AI Answer
All waves have: Amplitude (height, determines loudness/brightness), Wavelength λ (distance between crests), Frequency f (cycles per second, Hz), Period T = 1/f, Speed v = fλ. Sound waves are longitudinal (compressions and rarefactions). Speed of sound in air ≈ 343 m/s at 20°C. The Doppler effect: pitch increases as source approaches, decreases as it recedes. Standing waves form at resonant frequencies: f_n = nv/(2L).
