Задача 40166.

The oscillating points are located at a distance of 0.5 and 1.77 m from the oscillation source in the direction of wave propagation. The phase difference between their oscillations is 3p/4. The source oscillation frequency is 100 s^-1. Determine the wavelength and the speed of its propagation.

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
