Dispersion of White Light by a Glass Prism

The video tutorial explains the dispersion of white light through a glass prism. It describes how a prism splits white light into a spectrum of colors: violet, indigo, blue, green, yellow, orange, and red. This process, known as dispersion, occurs because different colors bend at different angles when passing through the prism. Red light bends the least, while violet bends the most, causing the colors to emerge along distinct paths.
