Which of the following is NOT one of the three bigness parameters?

Explanation:
The key idea is distinguishing quantities that describe how large or energetic a wave is from a property that describes its spacing. Amplitude tells you how tall the wave is at a point, power tells you how much energy flows per unit time, and intensity tells you how that energy is distributed over an area. These are all measures of magnitude or strength. Wavelength, however, describes the distance between successive peaks (the wave’s spatial or temporal period) and relates to color or frequency, not how big the wave’s energy is. So wavelength is the one that does not fit with the other three, making it the correct choice.
