Answer:
The answer is
[tex]4.92 \times {10}^{ - 22} \: J[/tex]
Explanation:
In order to find the energy of the wave we use the formula
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
f = 9.43 × 10¹¹ Hz
We have
[tex]e = 9.43 \times {10}^{11} \times 6.626 \times {10}^{ - 34} \\ [/tex]
We have the final answer as
[tex]4.92 \times {10}^{ - 22} \:J[/tex]
Hope this helps you
