(c) The energy change shown in the diagram represents the energy of red light and leads to a solution that appears blue. Blue light has a higher frequency than red light. Suggest whether the energy change ΔE will be bigger, smaller or the same for a transition metal ion that forms a red solution. Explain your answer.

In addition, we found that for plane waves B~ 0 = 1 ω ~k×E~ 0 (2) This equation implies that the magnetic field in a plane wave is completely determined by the electric field.

Instead, the momentum of a single photon is: Compton scattering: the photon transfers some of its energy to a particle (causing the particle to accelerate). energy, and therefore in its wavelength (since E = hν = hc/λ). Compton’s discovery of this effect (1923) was an important proof of the particle nature of light.

The wave nature of light is described by the equation c = λ·ν, which relates the speed of light (c, meters per second, m·s-1) to the wavelength (λ, lambda, meters, m) and the frequency (ν, nu, Hertz, Hz, s-1); because the speed of light is a constant in a given medium, wavelength and frequency are inversely proportional. 3.
