Requirements: 2 thermometers, black paint
Procedure: Paint 1 of the thermometers black and do not do anything with the 2nd one.
Keep both thermometers in sun for an hour or two. After an hour record the
temperature of both thermometers you will find that the one painted black
shows more temperature as compared to the second.
Conclusion: Dull colours are good absorbers of heat.

all atoms contain the same particle that produces the ray.
He proved that atoms are not full of a positive material but mainly open space.
Actually, it has been proved that light is bent by gravity, so it is impossible to prove that light travels in a straight line.
The classical definition says anything that occupies space is matter. To prove air occupies space we can do a small experiment. Take a balloon and blow air in it. The balloon expands and this proves that air occupies space. And thus we can prove air is matter.
An experiment can prove or disprove a hypothesis.
Prove causation
The colour of the dis when rotating is white it was an experiment to prove that white light was actually made of different colors and that experiment shows that if you get all the colours moving and spining fast enough it looks as if the light is white
Experiment
That depends on the result of the experiment. The experiment is a way to test a hypothesis, and it's completely fine if the experiment disproves the hypothesis. Ideally, though, the experiment will support the hypothesis.

This was an experiment to prove universal gravitation!
