C. The table below reflects what is usually understood by these names in the context of plant photobiology research. Light and ultraviolet radiation. The names of different spectral bands of importance in plant photobiology. The whole electromagnetic spectrum Light and ultraviolet radiation are just a small protion of the electromagnetic spectrum. The relationship between wavelength and frequency can be calculated with the applet writen by David Knespl in tcl, which also gives a graphical representation of the frequencies of different kinds of electromagnetic radiation.
Frequency is displayed on a logarithmic scale.
To get the numeric value of a frequency and corresponding wavelength and energy, click the left mouse button anywhere on the scale in the upper frame. The other two values will be displayed.
