Задача id309

The oscillating points located on the same beam are 6 and 8.7 m away from the oscillation source and oscillate with a phase difference of 3p/4. The source oscillation period is 10-2 s. What is the wavelength and speed of propagation of vibrations in this medium? Create a wave equation for the first and second points, considering the amplitudes of the points to be equal to 0.5 m.
