In this exercise you will figure out the index of refraction of a piece of glass by observing a light ray passing through glass into air and measuring the angles ${}_1$ and ${}_2.$ Note that index of refraction of air $(n_2)$ is $1.$ Watch the video in the time interval $0814-0$:$55$ and take measurements for $3$ different instances.
