Answer:
2.52 x [tex]10^{-23}[/tex] J
Explanation:
The energy given off by the microwave can be determined by the application of Planck's energy formula:
E = hf
where: E is the required energy, h is Planck's constant (6.626 x [tex]10^{-34}[/tex][tex]m^{2}[/tex]Kg/s), and f is the frequency (3.8 x [tex]10^{10}[/tex] Hz).
So that;
E = 6.626 x [tex]10^{-34}[/tex] x 3.8 x [tex]10^{10}[/tex]
= 2.51788 x [tex]10^{-23}[/tex]
Therefore, the energy released by the wave is 2.52 x [tex]10^{-23}[/tex] J.
