F: Fundamental Laws of Light Flashcards
The ration of the light
absorbed by a material to the light falling upon it is called
absorption
When light falls upon an opaque material, it is reflected.
When the material has a polished surface, the light will be
reflected at an angle equal to the angle of incidence.
specular reflection
When the material has an
unpolished surface, however, the reflected light is spread in
all directions by multiple reflections on the unpolished
surface.
diffuse reflection
The ratio of
reflected to incident light is called
reflectance
Upon translucent material,
however, such as plastic, the emerging light will
spread in all directions.
diffuse transmission
When the reduce light rays are distributed in all
directions with maximum intensity normal to the surface.
Diffusion
The property of the material to change direction of light
at the interface between two different materials, such as
air and glass.
Refraction
The phenomenon wherein the waves vibrates only in one
place.
Polarization
