A reflected ray is the light ray that bounces off a surface after striking it, following the law of reflection which states that the angle of incidence is equal to the angle of reflection. This fundamental concept is crucial in optics and is applicable in various phenomena such as mirror reflections, periscopes, and optical devices.

The law of reflection states that when a wave, such as light, hits a surface, the angle of incidence is equal to the angle of reflection. This principle is fundamental in understanding how mirrors work and is applicable to various types of waves, including sound and water waves.

law of reflection

The angle of incidence is the angle between an incoming wave or ray and the perpendicular to the surface it encounters. It plays a crucial role in determining how waves, such as light or sound, are reflected or refracted at interfaces between different media.

angle of incidence

The angle of reflection is the angle formed between the reflected ray and the normal to the surface at the point of incidence, and it is always equal to the angle of incidence according to the law of reflection. This principle is fundamental in optics and is crucial for understanding how light behaves when it encounters reflective surfaces.

Optics is the branch of physics that studies the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it. It encompasses phenomena such as reflection, refraction, diffraction, and interference, and is fundamental in technologies ranging from eyeglasses to advanced scientific instruments.

Optical devices are instruments that manipulate light to enhance or analyze visual information, commonly used in fields such as medicine, telecommunications, and photography. These devices utilize principles of optics to focus, magnify, or alter light paths, facilitating improved observation and data collection.
