Why do you use a discharge tube to perform the experiment instead a of light bulb?

It depends on the experiment, of course, but a discharge tube contains ionized atoms, while an incandescent simply has glowing metal. The former is, for most experiments, a lot more interesting.

What is the results of combining all colors of the visible spectrum?
You get white light. This is an instructive experiment to perform with a pair of prisms.
How can the technique of this experiment be used to determine whether any two different colors of light such as red light and blue light travel at the same speed inside the plastic?
Describe the experiment and its technique for me, and I'm likely to spot it.
What does a polarization experiment prove about light?
it explains d wave nature of light.
What was Albert Abraham Michelson's experiment?
Known as the Michelson and Morley experiment, this was an experiment to measure changes in the speed of light. Supposedly, as Earth travelled through the Ether, light would go faster in one direction than in the other (because of the relative velocities). The experiment didn't produce the expected result - the speed of light was found to be always the same. Today, this is an accepted fact - that the speed of light is the same for all observers - and is one of the bases for the Theory of Relativity.
How do you carry out a controlled experiment testing of the effect of green light versus blue light on plant growth?
you dont

Is there a chemical that can absorb light and then in the absence of light discharge that light?
There is no chemical that will absorb light and ONLY discharge it in the absense of light, however there are chemicals that will absorb light, store it as heat, and discharge it as light slowly, so that if light is removed it will continue to glow.
Is the green discharge dark or light?
its a light green discharge. kind of like cottage cheese.
How discharge tube is different from tube light?
discharge tube can be used for indentifying electrons while tube light cxannot

The rings may formd but the lack of intensity of light,the dark and light rings are not vissiable very well..
