La luz: espejos y lentes

The video tutorial explains the concept of mirrors and lenses. It begins by describing mirrors as objects with smooth surfaces that reflect light evenly, allowing us to see reflections. The tutorial then transitions to lenses, explaining that they are curved pieces of glass that refract light. Examples of lenses in everyday life, such as magnifiers, eyeglasses, and binoculars, are provided to illustrate their importance in enhancing vision and magnifying objects.
