The smallest angle of attack of an airfoil at which lift suddenly decreases and drag suddenly increases
The smallest angle of a ramp or stairs considered uncomfortable or unsafe
The smallest angle of incidence for which light is totally reflected from a boundary between one medium and a less refractive one
the smallest angle of incidence for which light is totally reflected
The critical angle is associated with refraction of light This angle is the smallest angle of incidence at which total internal reflection (TIR) occurs
The angle above which total internal reflection happens At angels lower than the critical angle, the light is refracted through the cladding
least angle of incidence for total reflection (Optics)
The minimum angle of incidence for which a light ray is totally reflected within a medium
When traveling from an optically denser to optically less dense material, the angle of incidence at which light stops being refracted and is totally reflected
the incidence angle corresponding to a 90 degree angle of refraction
In geometric optics, at a refractive boundary, the smallest angle of incidence at which total internal reflection occurs
Angle of incidence for which the angle of refraction is 90° when light goes from one medium of high index of refraction into one of lower index
The angle at the interface between core and cladding where a guided ray in the core undergoes total internal reflection
Minimum angle of incidence that produces total internal reflection
  In geometric optics, at a refractive boundary, the smallest angle of incidence at which total internal reflection occurs (188)  Note 1:   The angle of incidence is measured with respect to the normal at the refractive boundary   Note 2: The critical angle is given by
(qc) - qc = sin-1 (n2/n1), where n2 and n1 are the refractive indices of two materials at the interface (n2 being of the higher refractive material)
That limiting angle of incidence in the optically denser medium that results in an angle of refraction of 90o
Applies when light strikes a boundary between two materials and the speed of light in the material that it is travelling in is less than the speed of light in the material beyond the boundary If the angle of incidence at the boundary is greater than the critical angle, all the light is reflected
