Answer:
The answer is
[tex]3.77 \times {10}^{15} \: \: \: Hz[/tex]
Explanation:
The frequency of the photon can be found by using the formula
[tex]f = \frac{E}{h} \\ [/tex]
where
E is the energy
f is the frequency
h is the Planck's constant which is
6.626 × 10-³⁴ Js
From the question
E = 2.50 × 10^-18 J
So we have
[tex]f = \frac{2.50 \times {10}^{ - 18} }{6.626 \times {10}^{ - 34} } \\ [/tex]
We have the final answer as
[tex]3.77 \times {10}^{15} \: \: \: Hz[/tex]
Hope this helps you
