Electromagnetic waves, They are waves that can propagate in a vacuum, electromagnetic radiation, It is a type of variable electromagnetic field, that is, a combination of oscillating electric and magnetic fields, which propagate through space, transporting energy from one place to another., electromagnetic spectrum, energetic distribution of all electromagnetic waves., spectrum, electromagnetic radiation that emits (emission spectrum) or absorbs (absorption spectrum) a substance, photons, The energy carried by electromagnetic radiation travels by means of waves. This energy is not continuous, but is transmitted grouped in small "quanta" of energy, radiation, emission, propagation and transfer of energy in any medium in the form of electromagnetic waves or particles, geometric optics, It is based on the concept of a light ray as a path followed by material particles emitted by luminous bodies without worrying about studying the nature of light., physical optics, studies the luminous phenomena and investigates what is the nature of light., Light, A form of energy that illuminates things, makes them visible, and spreads through particles called photons., Reflection, occurs when light rays that hit a surface collide with it, deviate and return to the medium that they left forming an angle equal to that of the incident light,, Refraction, It is the change of direction and slowness that a wave experiences when passing from one medium to another with a different refractive index., optical fiber, A filament of dielectric material, such as glass or acrylic polymers, capable of conducting and transmitting light impulses from one end to the other
