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.
