As the wavelength of the radiations decreases, the frequency of the wave escalates. A high energy light will have a shorter wavelength than a low energy light. The vertical distance from the midpoint of a wave to a crest or trough is called the amplitude. So when the wavelength is increased, the energy is The higher the frequency, the more energy, and the higher the amplitude, the more energy. Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. The shorter the wavelength, the more energetic is the photon, the longer the wavelength, the less energetic is the photon. The amount of energy carried in each quantum is proportional to the frequency of the radiation. When amplitude increases, energy _____ a. increases b. decreases c. stays the same.
