How many correct experiments do we need to disprove a theory? How many do we need to prove a theory? Explain.
Solution 1DQ Step 1 To disprove a theory, one good experiment with strong and solid explanations is enough. While we are formulating a theory regarding a particular phenomenon or observation, it should be applicable for every feature related to that. If it is not, we cannot consider it as a theory. So, one strong experimental evidence is enough to disprove a theory. Example: Existence of the concept of ether. The concept of ether was proposed by Aristotle in earlier times. According to him, light is travelling through a medium called ether. After the development of Modern Physics, this concept of ether was rejected by the evidence which we have got from the Michelson-Morley experiment.
