What is the energy of joules of a photon with frequency 9.31x10^13Hz

what is the energy of joules of a photon with frequency 9.31x10^13Hz?

E = hf
E = (6.626 * 10^(-34) Js) * (9.31x10^13 Hz)
E = 6.17 × 10^(-20) J

Energy = h x v
h is contant = 6.626 x 10^-34 J.s
v = 9.31x10^13 Hz = 9.31x10^13 s^-1

E = 6.626 x 10^-34 J.s x 9.31x10^13 s^-1
E = 6.17 x 10^-20 J/Photon
