The distance between adjacent node and anti-node is equal to:
Correct answer: D. π/4
- A. π
- B. π/2
- C. 2π
- D. π/4
Explanation
The correct answer is π/4 because in wave motion, a node is a point of destructive interference where the amplitude is zero, and an anti-node is a point of constructive interference where the amplitude is maximum. The distance between a node and its adjacent anti-node is one quarter of the wavelength (π), as the wave oscillates between these two points in its cycle. The other options are incorrect because they either represent the full wavelength (π), half the wavelength (π/2), or double the wavelength (2π), which do not accurately describe the specific distance between a node and its adjacent anti-node.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fΞ»; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
