Multiple choice general knowledge science & technology

As the frequency of a spring wave is increased, the _____________

  1. velocity decreases

  2. velocity increases

  3. wavelength decreases

  4. wavelength increases
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The wave equation v = f × λ (velocity = frequency × wavelength) shows that if velocity stays constant and frequency increases, wavelength must decrease. They are inversely proportional. In a given medium, wave speed is fixed by the medium's properties.
