The Electromagnetic Spectrum

A photon is an example of _________ energy. Photons have ________ energy at short wavelengths and _________ energy at long wavelengths.a) kinetic; high; low.b) kinetic; low; high.c) potential; high; low.d) potential; low; high.

What is the Electromagnetic Spectrum?

The component of the electromagnetic spectrum that allows our eyes to visualize color is:a) X-rays.b) Gamma rays.c) Ultraviolet light (UV).d) Visible light.e) Infrared light.

 No. There is no such thing as an effective spectrum in reference to photosynthesis. 

 No. These are the wavelengths that are absorbed, not all of which are used for photosynthesis. 

 No. There are many forms of electromagnetic energy that are not useful in driving photosynthesis. 

 No. This encompasses many wavelengths, not all of which are effective at promoting photosynthesis. 

Consider the term used to refer to those wavelengths from which energy is used for photosynthesis.

Based on the work of Engelmann, a plot of photosynthetic activity versus wavelength of light is referred to as __________.

 No. Green is not the shortest wavelength. 

 No. Yellow is not the shortest wavelength. 

 No. Orange is not the shortest wavelength. 

 No. Red is not the shortest wavelength. 

Energy increases with decreasing wavelength.

A photon of which of these colors would carry the most energy?
