Light & Plants

Visible Light

Visible light can be described by its wavelength, the spatial period between repeating wave shape repeats.  Water waves, light waves, radio waves and sound waves are examples of phenomena described by wavelength.  Visible light is formed by electromagnetic waves and is only a small portion of the wave frequency spectrum.  

 

 

 

 

 

 

 

 

These waves have two main components, amplitude and frequency.    To learn more about waves click on the interactive link below.

Chlorophyll

Although Photosynthesis has 2 components, the Light Process/Reaction and Dark/Calvin Reaction, we will focus only on the Light Reaction in this module. 

You do not need to view all of the video below, but feel free to do so.  The first 7 min. and 20 sec. are the most important for our experiments.
