Which statement best describes the difference in energy between Wave X and Wave Y?

• The energy of Wave Y is less than the energy of Wave X because wave Y has a smaller wavelength.

• The energy of Wave Y greater than the energy of Wave X because wave Y has a larger amplitude.

• The energy of Wave Y is equal to the energy of wave X because they both have the same wavelength.
