The need of developing the technique is to improve the traditional measurement methods in measuring the state of stress in material by means of acoustoelasticity. The technique is based on measuring the transmission coefficient in proximity to the first and second critical angle of refraction and ...
Critical Angle: The critical angle is the angle of incidence to which the angle of refraction is equivalent to 90 degrees. Absolute internal reflection is the complete reflection of such a light ...

So the critical angle is defined as the angle of incidence that provides a 90 degree angle of refraction. Note that the critical angle is an angle of incidence value. For the water-air limit, the critical angle is 48.6 degrees. For the boundary between glass and crown water, the critical...

When the angle of incidence in water reaches a certain critical value, the refracted ray lies along the boundary, having an angle of refraction of 90-degrees. This angle of incidence is known as the critical angle; it is the largest angle of incidence for which refraction can still occur. ...

It occurs when angle of incidence is greater than a certain limiting angle, called critical angle.───当入射角大于某个称作临界角的极限角时, 便发生全内反射. At all angles than the critical angle, Both reflection and refraction occur.───对于所有小于临界角的入射角, 则既发生反射,又发生折...
