11. A wave of frequency 1000 hertz anc amplitude
0.005 mis trelling in a medium wüh a speed
of 300 ms? Write displacement-equation of the
oscillations due to this wave at a distance of 0.15 m
from the source. Ans.y = 0.005 sin (6280 - 3.14) m.
​

Answer 1

Answer:

A simple harmoinc progressive wave of amplitude 0.05 m and frequency 5Hz is travelling along the positive direction of x-axis with a speed of 40 m/s, then the displacement of a particle at 30 m from origin in the time 1 second will be
