What was the experiment of William Crookes?
His researches on electrical discharges through a rarefied gas led him to observe the dark space around the cathode, now called the Crookes dark space. He demonstrated that cathode rays travel in straight lines and produce phosphorescence and heat when they strike certain materials.

What is the limitations of Crookes tube?
These tubes had two major shortcomings in terms of their ability to produce X-rays. First, because the X-rays originated over a rather large area, the resulting X-ray images lacked sharpness. Second, the low intensity X-ray output required long exposures and these tubes could not hold up to the workload.
Did William Crookes win a Nobel Prize?

What discovered Dalton?
Dalton’s experiments on gases led to his discovery that the total pressure of a mixture of gases amounted to the sum of the partial pressures that each individual gas exerted while occupying the same space. In 1803 this scientific principle officially came to be known as Dalton’s Law of Partial Pressures.
What was discovered by Goldstein?
Anode ray
Eugen Goldstein/Inventions
He was primarily interested in electrical discharges in moderate to high vacuums. In 1886 he discovered what he termed Kanalstrahlen, or canal rays, also called positive rays; these are positively charged ions that are accelerated toward and through a perforated cathode in an evacuated tube.
What kind of experiments did William Crookes do?
Crookes had several conditions for his experiments, and he imposed them on the mediums he studied: It had to be his own selection of colleagues, friends, and spectators Crookes studied notable mediums, including Florence Cook , Daniel Dunglas Home, and Kate Fox. Crookes asserted that he witnessed varied paranormal phenomena, like the following:

When did William Crookes believe in the paranormal?
Interviews and letters show that Crookes was a believer in the paranormal until his death in 1919.
