The energy of the photon is 1.718 xx 10^(-26) "J"1.718×10−26J.

Explanation:

The energy of the photon is 1.718 xx 10^(-26) "J".

You use the formula E = (hc)/λ, where h is Planck's Constant, c is the speed of light, and lambda is the wavelength of the photon.

E = (hc)/lambda = (6.626 × 10^(-34)"J"*"s" xx 2.998 xx 10^8 "m"*"s"^(-1))/(11.56"m") = 1.718 xx 10^(-26) "J"
