Answer:
[tex]E=1.989*10^{-32}J[/tex]
Explanation:
From the question we are told that:
Frequency [tex]f=3 * 10 Hz[/tex]
Generally the equation for Energy of an electromagnetic wave is mathematically given by
[tex]E=hf[/tex]
Where
h=Planck's constant
[tex]h=6.62607015 * 10^{-34}[/tex]
Therefore
[tex]E=6.62607015 * 10^{-34}*3 * 10[/tex]
[tex]E=1.989*10^{-32}J[/tex]
