# What is the energy of a photon emitted with a wavelength of 448 nm?

##### 1 Answer

#### Explanation:

A **photon** is a particle of light that is released when an electron transitions from a *high* energy state to a *low* energy state.

The energy associated with the process is given by the following equation:

where

With the information given in the problem, it might at first seem as if the problem cannot be solved. However, **frequency**, **wavelength**,

Since the speed of light,
