Henri Becquerel was convinced that his hypothesis about the spontaneous emission of radiation from uranium was supported when he observed that uranium chloride crystals exposed to sunlight could fog a photographic plate wrapped in opaque paper. This suggested that something unseen was being emitted by the uranium that could cause this effect.

When was Matching hypothesis created?
The Matching hypothesis was first proposed by Elaine Hatfield and her colleagues in 1966. It posits that individuals are attracted to and form relationships with others who are of similar attractiveness and social desirability.
What scientists were involved in the discovery of radioactivity?
Marie Curie, Pierre Curie, and Henri Becquerel were key scientists involved in the discovery of radioactivity in the late 19th and early 20th centuries. Marie Curie's work with radioactive materials led to her pioneering research on radioactivity for which she was awarded Nobel Prizes in Physics and Chemistry.
How a hypothesis becomes a theory?
A hypothesis become a theory if it is proved by experimental data. tested; conclusion (apex)
How did Alexander Fleming use the scientific method?
Alexander Fleming used the scientific method by making observations of mold killing bacteria in a petri dish, forming a hypothesis that the mold could have antibacterial properties, testing this hypothesis through experiments, and analyzing the results to draw conclusions. His systematic approach led to the discovery of penicillin, the first antibiotic.
What is a hypothesis for fractional distillation?
A hypothesis for fractional distillation could be: "I hypothesize that fractional distillation will separate a mixture of liquids into its individual components based on their boiling points, with the lower boiling point component distilling off first and the higher boiling point component remaining in the flask, resulting in a purer distillate."
How do Becquerel's convinced at first that his hypothesis was supported?
Becquerel initially believed his hypothesis that phosphorescent materials produce X-rays when exposed to light was correct because he observed that the photographic plates placed next to uranium salts, a phosphorescent material, became fogged even when stored in the dark. This led him to conclude that some invisible radiation was being emitted from the uranium salts.
What do you do after you formed a hypothesis?
test your hypothesis.
When a hypothesis is supported by an experiment do we say that we have proven the experiment and it can become a theory?
That's the first step.
What is an scientific hypothesis?
A scientific hypothesis is an "educated guess" about a result or solution based on prior knowledge and observation. It is the first step in the scientific method. The hypothesis must be something that can be supported or defended through experimentation or observation.
How could Aristotle's hypothesis be supported or disproved?
Drop two balls with different weights and observe which ball hits the ground first.
What should a scientist do first if a hypothesis is not supported?
If a hypothesis is not supported, a scientist should first analyze the data to identify any patterns or inconsistencies that may explain the outcome. They should then consider revising the hypothesis based on these insights or exploring alternative explanations. It may also be beneficial to review the experimental design and methodology to ensure that the results are valid and reliable. Finally, conducting further experiments or gathering additional data can help clarify the situation.
Who discovered radiactivity?
Radioactivity was first discovered in 1896 by the French scientist Henri Becquerel.
What should a scientist do first if a hypothises is not supported?
If a hypothesis is not supported, a scientist should first carefully analyze the data to identify any potential errors or anomalies in the experiment. This may involve reviewing the methodology, checking for biases, or considering alternative explanations. Next, the scientist might revise the hypothesis based on the findings and conduct further experiments to test the new or modified hypothesis. It's also essential to communicate the results and their implications to the scientific community for feedback and further investigation.
What is a hyothcsis?
A hypothesis is an educated guess. In science, when you are given a question or if you want to examine something, you first have to question being asked, which is important to define. Then you need to decide what you think the answer is. This is your HYPOTHESIS. After you have it, you design an experiment to test it. Based on that experiment, decide whether or not your hypothesis is supported by your results. Then you can either adjust your hypothesis or figure out new ways to test it. Science marches on!
At first many scientists rejected Wegener and the hypothesis of continental drift. What was their main objection to his hypothesis?
The main objection to Wegener's hypothesis of continental drift was the lack of a plausible mechanism to explain how continents could move. Wegener's idea of continents plowing through solid oceanic crust was not supported by scientific knowledge at that time, leading many scientists to reject his hypothesis.
Who was the first person invented the radio?
The best answer if we have to limit it to a single individual is probably Henri Becquerel.
Can you please emphasize the scientific method?
The Scientific Method first starts with formulation of a question. Any question that is testable will do. The next step is to come up with an educated guess about your question. After the guess is made a prediction about the hypothesis (usually whether it is correct or not) is made. You then next test your Hypothesis using an experiment. After you test your Hypothesis you Analyse the data to discover whether or not the prediction about the Hypothesis is, or is not, supported.
