Before teachers introduce laser technology as a tool into the classroom, students should fully understand the basic knowledge of Optics and photonics. Light is primarily a particle, but it behaves like a wave. Visible light is diffuse and consists of multiple wavelengths, enabling us to distinguish the different colors of the world around us. Teachers can study in depth how light is produced at the atomic level - the energy released by electrons moving to different orbits - and how refraction and reflection work when light passes through different substances.
