Essay on Reflection and Refraction Lab
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.
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 …show more content…
We are secondly observing the general properties and characteristics of refraction. Refraction is defined as the change in speed of a wave due to being in a different medium. Pins were placed in a linear fashion along a chosen side of a square prism at a designated angle from the perpendicular. While viewing the virtual image through the opposite side of the square prism, more pins were placed in line with the virtual image, giving the illusion that there was only a single pin being viewed. To show the angle of refraction, the sites where both lines meet the sides of the prism were connected. All angles were measured from the perpendicular. Using Snell's Law and the measured angles, the
