The length between node and antinodes is:
Correct answer: A. λ/4
- A. λ/4
- B. λ/2
- C. λ
- D. 2λ
Explanation
(a) Option 1: The length between a node and an antinode is λ/4. This means that it is one-fourth of the wavelength. Nodes are points of no displacement, and antinodes are points of maximum displacement in a standing wave.(b) Option 2: The length between a node and an antinode is not λ/2. This option is incorrect. The correct answer is λ/4.(c) Option 3: The length between a node and an antinode is not λ. This option is incorrect. The correct answer is λ/4.(d) Option 4: The length between a node and an antinode is not 2λ. This option is incorrect. The correct answer is λ/4.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; 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.
