In a stationary wave, the distance between two consecutive nodes is equal to what fraction of the wavelength $\lambda$?

Solution

1. A stationary wave is formed by the superposition of two waves traveling in opposite directions.
2. Nodes are points where the displacement is always zero.
3. The distance between two consecutive nodes is defined as half the wavelength, $\frac{\lambda }{2}$.
4. Hence the answer is (C).
