In every instant of time, wavelength associated with a freely falling body:

Correct answer: A. Decreases

  • A. Decreases
  • B. Increases two times
  • C. Increases four times
  • D. Remains constant

Explanation

The wavelength associated with a freely falling body decreases as it falls faster (due to increasing velocity) over time. This illustrates the wave-particle duality of matter, where even macroscopic objects can have associated wavelengths, albeit extremely small.

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.
