A Monochromatic Light Source Illuminates a Double Slit and the Resulting

question 31

Multiple Choice

A monochromatic light source illuminates a double slit and the resulting interference pattern is observed on a distant screen. Let d = center-to-center slit spacing, a = individual slit width, D = screen-to-slit distance, adjacent dark line spacing in the interference pattern. The wavelength of the light is then:

Definitions:

Standard Deviation

An estimator for the amount of disparity or spread found in a set of numerical values.

Sample Mean

The average value of a subset of a larger population, used to estimate the population mean.

Finite Population Correction

A statistical adjustment applied when sampling without replacement from a finite population, to improve the accuracy of estimates like means and proportions.

Standard Error

A statistic that measures the dispersion of sample means around the population mean, often used to estimate the accuracy of a sample mean compared to the actual population mean.
