According to the conditions of the previous problem, find the distance between the nearest points of the wave oscillating in opposite phases. What is the phase shift between the oscillations of two points located along the beam at a distance of 37 cm? 37.13. The equation of a plane sound wave is s=6.0 10-6 Cos (1900t + 5.72x). Find the oscillation frequency, wavelength and speed of propagation. Compare the wavelength with the amplitude of the vibration, the speed of the wave with the amplitude of the vibration speed.
