What is the relationship between wavelength and energy of a photon of light?

Responses

  • The energy of a photon of light is always double the wavelength. 

    The energy of a photon of light is always double the wavelength.  - no response given

  • The wavelength equals the energy of the photon of light. For example, the energy of the wave = the energy of the light
