Some spectrums stimulate vegetative growth and others increase the yield in flowers and fruits. Other spectrums seem to have very little effect in plant growth. Thanks to the variable light spectrum available from LEDs we are finally starting to understand the relationship between light spectrum and plant growth. https://californialightworks.com | Ever since NASA began experimenting with LEDs for growing plants in the 1980s we have known that different light spectrums have widely varied effects on plants.

Can you think of a method to have the robot follow the line using turns? Describe how it would work.. 2. Pre-Activity Quiz. How does a light sensor work? Does the light sensor detect white or black as a higher amount of light reflectivity? Absorbance?. Dispersion of light. Visible light = full spectrum . wavelengths range from 400 nm to 700 nm. Different wavelengths have ever so slightly different indices of refraction when passing through materials such as glass, plastic, or water (and probably others). Light. Light. Properties and Interactions. What is Light?. Light. is a form of energy emitted by the Sun..  . What is Light?. Light. is a type of energy that travels as an electromagnetic wave..
