Investigating Refractive Index with Light and Glass Block

The video tutorial explains the concept of refraction, focusing on the angles of incidence and refraction as light passes through a glass block. It details an experiment setup to measure these angles and calculate the refractive index. The process involves tracing the light path, measuring angles with a protractor, calculating sine values, and plotting graphs to analyze the data. The tutorial concludes with determining the refractive index using the line of best fit on a graph of sine values.

Describe how to plot the results of the angles of incidence and refraction on a graph.

What is the formula for calculating the refractive index using the sine of the angles?

What is the relationship between the sine of the angle of incidence and the sine of the angle of refraction?
