From the equation of the wavelength, we can tell that the wavelength of a wave is inversely proportional to its frequency, i.e., as the frequency of a wave increases, its wavelength decreases. IV. if E increase f has to increase. The energy of a wave is directly proportional to its frequency. They might also note how small the energies are. Click Play, and then click Pause. As can be seen in the diagram above, as wavelength decreases (the waves become closer together), frequency increases (more waves in the same time frame). The amount of energy in a light wave is proportionally related to its frequency: High frequency light has high energy; low frequency light has low energy. Increasing energy E Increasing frequency v Increasing wavelength 2 Based on formulas and what was discussed in lecture, a) Is the relationship between wavelength and frequency direct or indirect? Wavelength the distance between any given point and the same point in the next wave cycle. They are related by = hc/ E photon where h is Plank's constant, c is the velocity of light and is the wavelength of the photon. An increase in frequency produces a proportional decrease in the wavelength of light with a corresponding increase in the energy of the photons that make up the light.
