Sample questions

1. 1.The minimum distance between two points having the same phase is called the:
   • A.wavelength
   • B.amplitude
   • C.period
   • D.frequency
2. 2.Newton's estimate of the speed of sound in air at STP (about 280 m/s) differs from the measured 331 m/s. The Laplace correction resolves this by replacing the bulk modulus P with:
   • A.gamma P, the adiabatic bulk modulus
   • B.P / gamma
   • C.2P, the doubled isothermal modulus
   • D.Y, the Young's modulus of air
3. 3.The speed of transverse waves on a stretched string depends on which properties of the string?
   • A.only the tension T and linear mass density mu
   • B.the frequency and wavelength of the wave
   • C.the amplitude of the wave only
   • D.the phase angle of the wave
4. 4.The standing wave y(x,t) = 2a sin(kx) cos(wt) differs from a travelling wave y = a sin(kx - wt) chiefly because:
   • A.the terms kx and wt appear separately, so the amplitude varies from point to point but every element oscillates with the same frequency
   • B.every element of the medium oscillates with a different frequency
   • C.the wave pattern moves steadily to the right
   • D.all elements have the same amplitude at all points
5. 5.![string_six_harmonics.png]() In the figure of normal modes of a string of length L fixed at both ends, mode (b) is labelled the second harmonic and is seen to contain two loops. If the wavelength of the standing wave in a mode is related to the string length by L = n(lambda/2), what is the wavelength of mode (b)?
   • A.2L
   • B.L
   • C.2L/3
   • D.L/2
