Definition and Basic Principles

The definition and basic principles revolving around the concept of angles of incidence form an integral part of our understanding of optics and reflection. In essence, the angle of incidence is described as the angle between an incoming wave or ray, often light or sound, and the perpendicular direction to the surface upon which it's incident, that is to say, impinging upon. This description is in line with the theory of optics, which is a branch of physics that deals with the properties and behaviors of light including its interactions with matter and the instruments used to detect it. The angle of incidence, denoted by the Greek letter 'i', is always measured from the normal (perpendicular line drawn from the surface where the incident ray hits) to the incident ray itself. The basic principle governing this angle of incidence can be encapsulated in the law of reflection. According to this law, for any given wave striking a surface, the angle of incidence is always equal to the angle of reflection, the latter which is the angle between the reflected ray and the perpendicular to the surface at the point of incidence. The concept of the angle of incidence is made prominent and most importantly used when a ray of light or sound wave moves from one medium, say air, into another medium, say water or glass. The change in speed of light or sound as it travels from one medium to another may lead to a change in direction, an effect known as refraction. Both the laws of reflection and refraction are dependent on the angle of incidence. Notably, these laws allow us to predict and explain a myriad of behaviors of light and sound. For instance, the working principles of mirrors, lenses, optical fibers, periscopes, echo phenomenon, the soothing effect of sunrise and sunset and most especially, in many medical and technology devices like ultrasound, RADAR, echocardiogram, and the like. An in-depth understanding of this angle of incidence, its definition, and its core underlying principles are indispensable to fully comprehend and appreciate different events and phenomena that are integral and practically relevant in our day-to-day lives.
