Question

The distance between the successive nodes is

• A. $\frac{\lambda }{4}$
• B. $\frac{\lambda }{2}$
• C. $\lambda$
• D. $2\lambda$

Answer 1

Answer: (B)

The characteristic of stationary wave is that some particles of the medium remains permanently at rest, while some other particles undergo maximum displacement compared to others. The former are called nodes while latter are called antinodes.
Distance between successive nodes = distance between successive antinodes. $=\frac{\lambda }{2}$
