WebSo the difference in energy ( ΔE) between any two orbits or energy levels is given by ΔE = En1 − En2 where n1 is the final orbit and n2 the initial orbit. Substituting from Bohr’s equation (Equation 6.3.3) for each energy value gives. ΔE = Efinal − Einitial = − ℜhc n2 2 − ( − ℜhc n2 1) = − ℜhc( 1 n2 2 − 1 n2 1) WebBy the equation E=h\nu E = hν, we have seen how the frequency of a light wave is proportional to its energy. At the beginning of the twentieth century, the discovery that energy is quantized led to the revelation that light is not …

WebThe speed of propagation vw is the distance the wave travels in a given time, which is one wavelength in a time of one period. In equation form, it is written as v w = λ T 13.3 or v w = f λ. 13.4 From this relationship, we see that in a medium where vw is constant, the higher the frequency, the smaller the wavelength. See Figure 13.8.
