The Energy E is the product of Planck's constant h and the frequency v. (The actual notation is the Greek letter "nu", but allow me to use the "v" here:

E = hv

The value of h is 6.626 x 10^(-34) joule-second

Multiplying:

6.626 (10E-34) 4.3 (10E14)

simplifies to:

28.49 E-20

or:

2.849 * 10^(-19) joule
