Responses
Wave A has more energy than Wave B because the wavelength of Wave A is greater.
Wave A has more energy than Wave B because the wavelength of Wave A is greater.
Wave B has more energy than Wave A because the frequency of Wave B is greater.
Wave B has more energy than Wave A because the frequency of Wave B is greater.
Wave B has more energy: the amplitude of Wave B is double that of Wave A.
Wave B has more energy: the amplitude of Wave B is double that of Wave A.
Wave energy is directly proportional to frequency and wavelength, therefore Wave A has more energy.
The correct response is:
Wave B has more energy: the amplitude of Wave B is double that of Wave A.
The energy of a wave is directly proportional to its amplitude. The amplitude of a wave represents the maximum displacement of the particles of the medium, or the maximum disturbance of the wave. In this case, Wave B has a higher amplitude, which means that it has a greater maximum displacement or disturbance compared to Wave A. Therefore, Wave B has more energy.
The wavelength and frequency of a wave do not directly determine its energy. While wave energy is related to frequency and wavelength through the wave equation (energy = Planck's constant x frequency), it is the amplitude that primarily determines the energy of a wave.
