34. The standing wave is formed by applying the traveling wave and the wave reflected from the interface perpendicular to the direction of wave propagation. Find position (the distance from the interface) nodes and antinodes of the standing wave when the reflection occurs: 1) the environment less dense; 2) from the denser medium. Υ speed of sound vibrations is 340 m / s and the frequency ν = 3,4 kHz.
