A wave represented by the given equation 
is superposed with another wave to form a stationary wave such that the point x = 0 is a node. The equation for the other wave is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Since the point 
is a node and reflection is taking place from point 
This means that reflection must be taking place from the fixed end and hence the reflected ray must suffer an additional phase change of π π or a path change of 
So, if
