Plane Mirrors

Plane Mirrors. The Ray Model of Light. Light sources radiate light in all directions. The direction in which light travels is represented by lines with arrows (rays) on diagrams. . The basic property of light is that when it travels within the same medium, it moves in straight lines.

Optical Refraction

Optical Refraction . Optical Density is a property of a transparent material that is inverse to the speed of light through the material. i = angle of incidence. normal. r = angle of refraction. i. incident ray. Air. r. Water. refracted ray.

11.6 The Laws of Reflection

11.6 The Laws of Reflection. The angle of incidence equals the angle of reflection The incident ray, the reflected ray, and the normal are all in the same plane. Reflecting Light Off Surfaces. Specular Reflection: reflection off a smooth/shiny surface.

b)Limiting angle (critical angle)

(-I-) a) medium 1 is the more refractive medium because the refracted ray deviated away from the normal . OR. b)Limiting angle (critical angle). d) = , then the incident ray is reflected. ( Total internal reflection ) .
