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.
Think of it this way, 1 hour=60 minutes.
60 minutesx4 is equal to 240 minutes.
So, your answer is C.240 minutes.
