If the frequency of a wave is doubled while the speed remains constant, its wavelength becomes:
Correct answer: B. Halved
- A. Doubled
- B. Halved
- C. Unchanged
- D. Four times
Explanation
If the wave speed stays constant, doubling the frequency makes the wavelength half.

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.
