Reflection And Refraction Lab
OBJECTIVE
The objective of this experiment is to study refraction and reflection and also to use Snell's law correctly to determine the optical properties and indices of refraction for a prism.
DATA
All data is included in an excel spreadsheet, attached to this write-up.
Some uncertainties that see probable in the case of general human error are the basic visualization of the location of the pin, the measuring of the angles with a protractor, the possibly imprecise way to draw the reflected and incident rays and a general error in calculation. It is also possible that some uncertainties were caused by equipment imperfections, such as the mirrors being warped or the pins being bent. Also, some protractors were more precise and easily read, while others were not.
RESULTS
µ=∑(x) , where µ= mean in cm (also referred to as ), ∑= summation, x= the actual numbers obtained in the data set recorded in ohms, n= the number of data points.
