Question

What is the energy of an electromagnetic wave with a frequency of 8•10^12 Hz?

Answer 1

Hello!

Find the Energy of the Photon by Planck's Equation, given:

E (photon energy) =? (in Joule)

h (Planck's constant) =
`6.626*10^(-34)\:J * s`

f (radiation frequency) =
`8*10^(12)\:Hz`

Therefore, we have:

`E = h*f`

`E = 6.626*10^(-34)*8*10^(12)`

`E = 53.008*10^(-34+12)`

`E = 53.008*10^(-22)`

`\boxed{\boxed{E = 5.3008*10^(-21)\:Joule}}\end{array}}\qquad\checkmark`

I Hope this helps, greetings ... DexteR! =)
