Law of Reflection Concepts

The video tutorial introduces the law of reflection, explaining that the angle of incidence is equal to the angle of reflection. This principle is applied in scenarios involving mirrors and light bouncing off surfaces. An example is provided to illustrate the concept, showing how light reflects off a flat surface. The tutorial concludes with an invitation to join the community and subscribe for more lessons.
