In a periodic wave, the distance between two consecutive crests is known as _.

Correct answer: A. Wavelength

  • A. Wavelength
  • B. Amplitude
  • C. Displacement
  • D. None of these

Explanation

Correct Option:AIn a periodic wave, the distance between two consecutive crests (or two consecutive troughs) is known as the wavelength. The wavelength is a fundamental property of a wave and represents the spatial length of one complete cycle of the wave pattern.

About Progressive Waves

Progressive waves transfer energy through a medium or space while particles oscillate about their equilibrium positions. The work includes amplitude, wavelength, frequency, period, phase difference, wave speed and the progressive wave equation, while distinguishing travelling waves from stationary waves, where the pattern has fixed nodes and antinodes.
