A sound wave of wavelength 40 cm travels in air. If the difference between the maximum and minimum pressures at a given point is 10 x 10 -'N/m, find the amplitude of vibration of the particles of the medium. The bulk modulus of air is l'4 x 10 Nm.

A periodic vibration at x = 0, t = 0 displaces air molecules along the x direction by smax = 3.2E-05 m. The motion produces a sound wave that travels at a velocity of v = 336 m/s with a frequency of f = 120 Hz. Take the density of air as ρa = 1.20 kg/m3. Calculate the displacement of the air molecules using an function for the traveling sound wave in terms of time and position at time t = 0.001 s and displacement x = 1.0 m.  Write an expression for the maximum pressure exerted by the sound wave ΔPmax in terms of the air density ρa, the sound velocity v, the angular frequency ω, and the maximum displacement smax. The sound wave is directly incident on a sheet of paper of surface area A = 0.013 m2. Calculate the maximum force Fmax, in newtons, exerted on this sheet.

What`s frequency of 4th harmonic YAG:Nd3+ laser beam if it`s wavelength is 266.0 nm. Introduce answer in THz.

Find the pressure amplitude (in Pa) of a 1.40 kHz sound wave in air, given that the displacement amplitude is 2.30 x 10-8 m. [Note: The equilibrium density of air is p pressure, 1.013 × 105 Pa.] 8.32 Use the relationship between s max and ΔΡ 1.20 kg/m³ and the speed of sound in air is v = 343 m/s. Pressure variations AP are measured relative to atmospheric max' You will need to convert frequency to angular frequency. Don't forget to convert units as needed. Pa
