Question

What does the length of the red line represent in the picture of the wave shown below?

  1. Frequency 
  2. Wavelength
  3. Amplitude
  4. Time

hintHint:

Height of the wave.

The correct answer is: Amplitude


    • Amplitude is the maximum height of a point from its mean position in a wave form.
    • So, the correct option is c.
