From these equations you may realize that as the frequency increases, the wavelength gets shorter. Let the positive x direction be east and the positive y direction be north. We can also observe that the waves are produced with a shorter wavelength. Frequency and wavelength are inverse correlated by way of the speed of light (c): Light emitted from the Sun is the product of black body radiation from the intense heat generated by nuclear fusion processes within its core (in-depth reference from Uppsala University can be found here). Inversely proportional (when one increases, the other decreases) Question 3. Similarly, as the frequency of a wave decreases, its wavelength increases. The relationship between wavelength and frequency is called an inverse relationship, because as the frequency increases, the wavelength decreases. The wavelength of the second wave ( 2) =? See Figure 13.8. The crest is the highest point of the wave, whereas the lowest point of the wave is the trough. The relation that we now believe to be correct is that the wavelength of the photon decreases as the energy of the photon increases. The green pigment, chlorophyll, restricts the efficiency of photosyn As frequency increases, wavelength decreases.
