Calculate the energy of one photon of (a) ultraviolet light (λ = 1x10-8 m); (b) visible light (λ = 5x10-7 m); and (c) infrared light (λ = 1x10-4 m). What do the answers indicate about the relationship between light's wavelength and energy?

63 x 10^-34 Js), c is the speed of light (3 x 10^8 m/s), and λ is the wavelength of the light. Now, let's calculate the energy for each type of light: (a) Ultraviolet light (λ = 1 x 10^-8 m): E = (6.63 x 10^-34 Js) * (3 x 10^8 m/s) / (1 x 10^-8 m) E = 1.989 x Show more…
