Review Chapter 16 Waves Longitudinal Waves Transverse Waves Know the relation between wavelength, frequency, period, speed Transverse wave on a string. Know how to calculate the velocity. Power - proportional to the square of the amplitude. Intensity =power/area Superposition principle. Interference – know how to calculate the conditions for constructive and destructive interference. Beat frequency- the difference between two frequencies. F v = µ v f = λ 1 f T =

Chapter 17 Sound Speed of sound in a gas (speed of sound in air at 20 C= 340 m/s) Intensity of sound Decibels (dB) Speed of sound in a solid Phase shift on reflection. Standing Waves. Know how to find f, λ for different boundary conditions. e,g. P v γ = ρ o I I 10log ⎛⎞ β= ⎜⎟ ⎝⎠ B ρ I o = 10 -12 W/m 2 m=1 m=3 4L λ= f=v/4L Doppler effect. know the difference between moving source and moving observer. f f' (1 u / v) = ± f' f(1 u/v) = ± moving source moving observer
