What frequency does a photon of wavelength #4.5 * 10^-4# #m# have? Chemistry Bohr Model of the Atom Calculations with wavelength and frequency 1 Answer Sam May 23, 2016 #nu= 6.7xx10^11\ sec^-1# Explanation: # nu=c/lambda# #nu -> "frequency in "sec^-1# # c -> "speed of light = " 2.998xx10^8 \ m //sec# # lambda ->"wave length = " 4.5xx10^-4 \ m# #nu=(2.998xx10^8\ m//s)/(4.5xx10^-4\ m)# #nu=(2.998xx10^8\ cancel(m)//s)/(4.5xx10^-4\ cancel(m))# #nu= 6.7xx10^11\ sec^-1# Answer link Related questions Question #f2711 Question #6b062 Question #6b066 What is the formula for frequency?
