Exploring the principles of light reflection, this overview discusses specular and diffuse reflection, the fundamental laws governing the behavior of light, and the impact on color perception. It highlights reflection's importance in visual perception and its application in other wave phenomena like sound and water waves.

Light reflection is the redirection of light rays when they encounter a boundary between two distinct media
First Law
The first law of light reflection states that the incident ray, the reflected ray, and the normal to the reflection surface all lie in the same plane
Second Law
The second law of light reflection states that the angle of incidence is equal to the angle of reflection
Third Law
The third law of light reflection states that the reflected ray and the incident ray are on opposite sides of the normal
Light reflection can be categorized into specular and diffuse reflection based on the nature of the reflective surface
Specular reflection occurs on smooth, polished surfaces where the surface normals are parallel or consistently oriented, resulting in clear, sharp images
Virtual images are produced by specular reflection and appear to be located behind the reflective surface
The perceived color of objects is a result of selective light reflection, where objects reflect certain frequencies of light while absorbing others
Diffuse reflection occurs on rough, irregular surfaces where the surface normals are randomly oriented, causing reflected rays to scatter in multiple directions
The perceived texture and color of objects are a result of diffuse reflection
The principles of diffuse reflection are applicable to other wave types, such as sound and water waves

Definition of light reflection
Phenomenon where light rays hit a boundary between two media and bounce back into the original medium.
01
Reflective surface characteristics
The boundary where light reflection occurs, can be smooth like a mirror or irregular causing diffuse reflection.
02
Categories of reflection
Two types: specular reflection from smooth surfaces, and diffuse reflection from rough surfaces.
