$3.97 \cdot {10}^{-} 19 J$

#### Explanation:

$E = h \cdot f$

Where
$h = \text{Planck's constant} \left(6.62 \cdot {10}^{-} 34 \frac{J}{s}\right)$
$f = \text{frequency}$

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
