Task 1
Overlapping of waves
as a result, in an elastic environment where their maximum attenuation is observed
of two coherent waves
to elastic midpoints
the difference of minimum propagation paths up to
find out. Sources of waves
It oscillates in the same phase with a frequency of 0.4 kHz. Wave propagation in a given medium
speed is 240 m/s.
Task 2
Of two coherent waves
the first of the given environment
16 m from the wave source and
31 m away from the other
at the location point
the result of interference
find out. Sources of waves
Same as 20ms period
oscillates in phase. Of the wave
propagation speed is 1.5 km/s.
