A) \[\lambda =\pi {{y}_{0}}\]
B) \[\lambda =\frac{\pi {{y}_{0}}}{2}\]
C) \[\lambda =\frac{\pi {{y}_{0}}}{2}\]
D) \[\lambda =2pi{{y}_{0}}\]
Correct Answer: A
Solution :
Comparing the given equation to the standard equation of wave \[\omega {{y}_{0}}=2v\] \[2\pi n{{y}_{0}}=2n\lambda ,\] hence\[\lambda =\pi {{y}_{0}}\]
