A nonrelativistic electron is accelerated from rest through a potential difference. After acceleration the electron has a de Broglie wavelength of 880 nm. What is the potential difference though which this electron was accelerated? (h = 6.626 × 10-34 J ∙ s, e = - 1.60 × 10-19 C, mel = 9.11 × 10-31 kg)
σ
The symbol for standard deviation, a measure of the amount of variation or dispersion of a set of values.
Normal Distribution
A symmetric probability distribution centered on the mean, demonstrating that occurrences near the mean happen more often than those far from it.
Maximum Oxygen Uptake
The maximum rate at which an individual can consume oxygen during intense or maximal exercise, indicating cardiorespiratory fitness.
Alternative Hypothesis
A statement in hypothesis testing that proposes a difference or effect, opposing the null hypothesis which suggests no effect or difference.
