Magine a thin layer of water (n = 1.33) spread across a block of ice (n = 1.309). (a) if rays of light are directed downwards and reflect/refract with respect to the thin layer of water, determine the minimum water thickness that produces the least reflection at a wavelength of 550 nm. (b) suppose a flashlight was turned on and frozen in the block of ice pointing upwards, determine the minimum water thickness that produces the most reflection at a wavelength of 650 nm.

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
