The video tutorial explores the concepts of reflection and refraction through an experiment involving a Perspex block. Key terms such as angles of incidence, reflection, and refraction are defined. The experiment setup is demonstrated, followed by conducting the experiment to observe how changing the angle of incidence affects the angles of reflection and refraction. Measurements are taken, and conclusions are drawn, highlighting that the angle of reflection is approximately equal to the angle of incidence, and the angle of refraction is always smaller than the angle of incidence when light passes from air to Perspex.
