WebE = hc / λ--- use this equation when asked to calculate E after being given the wavelength. Rearrange to group the variables and the constants: Eλ = hc (d) The mathematical relationship is an inverse one. Note the equation's similarity to λν = c, with two values that can vary on the left side and a constant (h times c) on the right. WebApr 23, 2024 · Also to explain E=hc/wavelength. E=hc/wavelength comes from the c=frequency times wavelength. When you experiment with the equation and you get frequency equals speed of light/ wavelength since E=h(frequency). Therefore you would get E=hc/wavelength. I hope this helps. Correct me as I might be wrong in some places.
