Asked in NUMS 2022 2022

Tho horizontal distance travellled by wave during one complete cycle Is called

Correct answer: B. Wavelength

  • A. Frequency
  • B. Wavelength
  • C. Amplitude
  • D. Time period

Explanation

The wavelength (λ) is the total distance travelled by the wave in one full cycle. In this case, the wavelength can be given by horizontal distance between repeating units of the wave pattern.

About Wave Speed

Wave speed is the rate at which a disturbance or wave pattern travels through a medium, given by v = fλ, where f is frequency and λ is wavelength. Questions examine how speed changes between media, the relation among frequency, wavelength and period, and why wave speed is not the same as particle vibration speed.
