A "Negative Experiment" is one where the expected result of the experiment is not found. These experiments are critically important and represent important work in Physics. The Michelson-Morley experiment, a "negative experiment" is one of the most important in the history of science. It was an test to measure the influence of the presumed etheric medium on a beam of light. No effect was found. Thus no ether.

What are positive and negative controls in an experiment?
Positive controls : an experimental treatment that will give the desired result Negative controls: An experimental treatment that will NOT give the dersired result.
Is the probability of an event in an empirical experiment may change from experiment to experiment?
Yes.
Why must a controlled experiment have one manipulated variable?
a controlled experiment must have only one manipulated variable becuase if the experiment had multiple manipulated variables then it would not be a controlled experiment anymore it would be a manipulated Deseret experiment
What is being measured in a science experiment?
in a science experiment many things are measured. it depends on what experiment one is conducting.
Why is the snorg hypothesis not scientific?
There is no experiment or possible evidence that could prove that invisible snorgs do not exist. So the Snorg Hypothesis is not scientific. On the other hand, the "Negative Snorg Hypothesis" (that they do not exist) is scientific. You can disprove it by catching one.
What results from an experiment do you mistrust if your negative control is not as expected?
nothing
What did Robert milikan contribute in science?
he discovered the the electron has a negative charge through an experiment called the oil-drop experiment
Why there is gap in tunnel diode voltage in experiment?
negative resistance region
In a scientific experiment what is the definition of a variable?
Pretty much as it is in math, something that is undefined, but in Science it needs to be defined or the experiment cant continue. Your variables are basically what you measure, what you change and your control, both positive and negative (one with a 100% percent positive result and another with a 100% negative result)
What happens if the experiment dose not confirm hypothesis?
This indicates that the hypothesis is probably incorrect and a new hypothesis needs to be developed. A negative result for a scientific experiment is just as important as a positive result and means that the experiment was a success.
What are positive and negative controls in an experiment?
Positive controls : an experimental treatment that will give the desired result Negative controls: An experimental treatment that will NOT give the dersired result.
In thompsons experiment why was the glowing beam repelled by a negatively charged plate?
Because their where negative charges or particles in the beam
How did Benjamin Franklin discover positive and negative charges?
Benjamin Franklin is famous for his experiments with electricity. Unfortunately, records don't contain a particular experiment where he discovered positive and negative charges.
How do you find positive and negative charged ions?
If the number of electrones and prorons are the same they are NOT iones. Or are you asking how to find them in a chemistry experiment?
Who calculated the negative charge of an electron?
The brilliant, so-called "Oil-drop experiment" of Robert A. Millikan established the magnitude of the quantum of electric charge ... the amount of charge on each electron (negative) and each proton (positive). Search around on line for "Millikan oil drop experiment" to read the fascinating story of how it was done.
Which scientist is credited with discovering the electron?
J.J Thompson discovered the electron. He also performed the Cathode Ray Tube Experiment and that told him that electrons are negative J.J Thompson discovered the electron. He also performed the Cathode Ray Tube Experiment and that told him that electrons are negative
What's a negative control?
A negative control is a control group in an experiment where the variables are not expected to have an effect. It helps researchers to determine if any observed effects are due to the treatment being tested or other factors.
