How much energy is in a wave that has a wavelength of 1.3 pm? Chemistry Bohr Model of the Atom Calculations with wavelength and frequency 1 Answer anor277 Oct 19, 2016 #epsilon=hnu#, where #h="Planck's constant"=6.626xx10^(-34)J*s# Explanation: Here #nu=c/lambda# and thus #epsilon=nuxx6.626xx10^(-34)J*s# #=(3.00xx10^8*ms^-1xx6.626xx10^(-34)J*s)/(1.3xx10^-12m)#. This calculation gives an answer in #"Joules"# as required. Answer link Related questions Question #f2711 Question #6b062 Question #6b066 What is the formula for frequency?
