PPT-What is Light?

1 0 1 What is Light The sun emits large amounts of energy in all directions Some of this solar energy reaches Earth and heats the Earths surface SOURCES a Natural ex sun fireflies. If a visual system only made a single measurement of luminance acting as a pho tometer then there would be no way to distinguish a white surface in dim light from a black surface in bright light et humans can usually do so and this skill is known as U. tility.

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. Light. Light. Properties and Interactions.
