Visible light falls into wavelength ranges of 400-700 nm, for which 

. 

The energy and wavelength of light are related by the equation

where 

 is energy in Joules, 

 is Planck's constant (

), 

 is the speed of light (

), and 

 is the wavelength in m.

If a visible light photon has a wavelength of 452.2 nm, what is the energy of the photon (in J)?
