Answer:
[tex]u=4.57x10^5GHz[/tex]
Explanation:
Hello.
In this case, given the formula:
[tex]E=h*u[/tex]
Whereas E is the energy, h the Planck's constant and u the frequency of the photon. Thus, solving for it, we obtain:
[tex]u=\frac{E}{h}=\frac{3.03x10^{-19}J}{6.63x10^{-34}J*s}\\ \\u=4.57x10^{14}s^{-1}[/tex]
Or also:
[tex]u=4.57x10^{14}Hz*\frac{1GHz}{1x10^9Hz}\\ \\u=4.57x10^5GHz[/tex]
Best regards.
