133. Problem 17.47E (HRW) Two sinusoidal waves with identical wavelengths and
amplitudes travel in opposite directions along a string with a speed of
|
. The
time interval between instants when the string is flat is 0.50 s. We have
to find the wavelength of the waves.|
Solution: Click For PDF Version As the two identical waves are moving along a string in
opposite directions with a speed of
The resultant wave is
The time interval T between instants when the string is flat is 0. 50 s. This implies
