As speed= dist/time, V=lambda/t As nu=1/t, V=lambda × nu As speed of light is denoted as C, we get, C= lambda × nu So, as a result, we get Nu= C/lambda As, E=h×nu, E=h×C/lambda OR E=hC/wavelength

Also, if you want, you may also get the value of energy if the wavelength is divided by 12.41×10^-7 E= [(12.41×10^-7)/wavelength]
