Question

A wave of length 2 m is superposed on its reflected wave to form a stationary wave. A node is located atx = 3m; the next node will be located at x equal to –

• A. 3.25 m
• B. 3.50 m
• C. 3.75 m
• D. 4 m

Answer 1

Answer: (D)

4 m

Answer 2

The distance between two consecutive nodes is $\frac{\lambda}{2}$

Q l = 2

\ Distance between two consecutive

nodes = $\frac{2}{2}$= 1

So next node is at x = 4m.
