Answer:
[tex]2.9\cdot 10^{-18} J[/tex]
Explanation:
The energy of a photon is given by:
[tex]E=hf[/tex]
where
h is the Planck constant
f is the frequency of the photon
In this problem, we have:
[tex]h = 6.63\cdot 10^{-34} Js[/tex]
[tex]f=4.4\cdot 10^{15} Hz[/tex] is the frequency of the photon
Substituting into the equation, we find:
[tex]E=(6.63\cdot 10^{-34} Js)(4.4\cdot 10^{15} Hz)=2.9\cdot 10^{-18} J[/tex]
