Question #143e8

Answer 1

`3.97*10^-19 J`

Explanation:

`E = h*f`

Where
`h = "Planck's constant" (6.62 * 10^-34 J/s)`
`f = "frequency"`

This equation describes the energy associated with a photon - a particle of electromagnetic radiation.

Green light falls under visible light in the EM spectrum. It has a certain frequency and its frequency is directly proportional to the amount of Energy it carries.

To solve, just plug in.

`E = (6.62 * 10^-34 J*cancels) * (6.00×10^14 cancel(s^-1)) = 3.97*10^-19 J`

Answer: 3.97*10^-19 J
