These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. (a) The speed of the radiation decreases. How does wavelength affect energy of a wave? Step 2: Explanation. That is, when the wavelength increases, energy decreases and when the wavelength decreases, energy increases. Putting a lot of energy into a transverse pulse will not effect the wavelength, the frequency or the speed of the pulse. As the wavelength of a wave increases, which is also true? A high energy wave is characterized by a high amplitude; a low energy wave is characterized by a low amplitude. The pitch of the sound increases. The energy associated with a wave is directly proportional to its frequency. See Figure 13.8. 8. What happens to the frequency and wavelength of electromagnetic waves as the wave energy increases from radio to gamma? As the frequency decreases, the wavelength gets longer.
