Section-E: Numerical Problems
A wave generator at one end of a very long string creates a wave given by
y1 = (6.0 cm) cos [(20 m–1)x + (8.00 s–1)t]
and a wave generator at the other end creates the wave
y2 = (6.0 cm) cos [(20 m–1)x – (8.00 s–1) t].
for x > 0, what is the location of the node (in cm) having the smallest value of x.
