Answer: The correct answer is energy of the wave.
Step-by-step explanation:
Wavelength: It is the distance between the two consecutive crests or troughs.
Frequency: It is the number of waves per second. Mathematically, it is represented by

Here, T is the time period and
is the frequency.
Heights of the wave represents the amplitude of the wave. The energy of the wave is directly proportional to the square of the amplitude of the wave.
The energy of the wave is represented by the expression as

Here,
is the frequency of the wave and h is the Planck's constant.
Therefore, the height, length and period of a wave comprise the energy.
