1. The problem statement, all variables and given/known data If you were to measure ten identical measurements, would that imply that your measurement of the wavelength had no uncertainty? what would the uncertainty of the measurement be in that case? 2. Relevant equations n/a 3. The attempt at a solution I am thinking no because there would still be the presence of systematic uncertainties, ie flaws within the design of the experiment. But the problem seems to imply that there is a specific number, which is the part which I'm unsure of. Am I on the right track?
