Explanation:
Wave is a disorder that travels through the medium periodically, carrying energy, but not matter. Five parameters determine waves: period, frequency, amplitude, wavelength, and speed. The amount of energy the wave carries is determined by the amplitude. The high amplitude wave possesses a high level of energy, a wave with a small amplitude carries a small amount of energy. In addition, the amplitude does not affect the speed of the waves; both Waves A and B travel at the same speed. The velocity of the wave changes with the characteristics of the media through which they pass.
Right answer is B) the amplitude of the waves.
