Physics 2415 Lecture 31 Michael Fowler UVa Todays Topics Dipole radiation Photons Reflection and image formation by a plane mirror Concave and convex mirrors Dipole Radiation A static dipole field looks like this. 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.
