Before changing a fluorescent light bulb that was not going on
immediately, I noticed waves (dark and light regions with the light
regions about 3 times larger than the dark ones) moving slowly across
the 30 inch bulb. The wavelength was about 2 inches and the set of
waves were moving slowly to the right.
Please explain.
