Then an interesting phenomenon called "Total internal reflection" takes place. Here the incident wave is totally reflected inside the medium as if it were reflected from the boundary of an opaque solid. For more details, contact at saqibahmad81@Yahoo.com

What will happen if the angle of incidence is bigger than the critical angle?
A complete reflection will occur
Is the critical angle the same thing as the angle of incidence?
The critical angle is not the same thing as the angle of incidence. There is a reason the confusion. The critical angle is defined as the smallest angle of incidence which results in total internal reflection. Every plane wave incident on a flat surface has an angle of incidence. That can be any angle. When a wave travels from a dense medium to a less dense medium, there comes an angle of incidence where there is no transmission into the less dense medium. We say then that for an angle of incidence above the "critical angle" the result is total internal reflection. It is also true that with Snell's law, the critical angle is the particular angle of incidence which would result in a 90 degree angle of refraction.
When a light ray is reflected by a mirror is the angle of the light ray and the reflected ray different or the same?
Angle of Incidence = Angle of ReflectionThis is only true if the angle of incidence is greaterthan the critical angle.
What tajes place when the angle of incidence is smaller than the critical angle?
Refraction and partial internal reflection occurs
When the angle of incidence is greater than the critical angle all light within the material is?
hte light is reflected
What will happen if the angle of incidence is bigger than the critical angle?
A complete reflection will occur
What name is given to the angle where total internal reflection occurs?
Total internal reflection occurs when the angle of incidence with respect to the normal at the boundary to a less dense medium exceeds the critical angle.

What is the definition of critical angle?
The definition of critical angle is the angle of incidence that refraction can still occur.
Define critical angle?
critical angle is defined as angle of incidence provide an anlge of refraction of 90 degree
What is meant by the critical angle?
A 'critical angle', is bascially the smallest angle of incidence for which light can be totally reflected. Incidence is the arrival of a particle or beam of light at a surface. I.e. If a beam of light hits a desktop at the angle of 45 degrees, the angle of incidence will be 45 degrees.
What is the critical angel?
The critical angel is the angle of incidence that yields an angel of refraction that is larger than the angels of incidence.
When a light ray is reflected by a mirror is the angle of the light ray and the reflected ray different or the same?
Angle of Incidence = Angle of ReflectionThis is only true if the angle of incidence is greaterthan the critical angle.
If angle of incidence equals critical angle what is angle of refraction?
90o. i think there will be no refraction there will be totally internal reflection
When the angle of incidence is greater than the critical angle all light within the material is?
hte light is reflected
What tajes place when the angle of incidence is smaller than the critical angle?
Refraction and partial internal reflection occurs
The angle of reflection is equal to the .......?
The angle of incidence
