hte light is reflected
it is not the angle of total reflection, it is the critical angle. and when the angle of incidence is greater than the critical angle, total internal reflection takes place and as it is necessary for total internal reflection to take place that the ray must travel from denser to rarer medium so, when it occurs, the ray is reflected bach into the denser medium.
It does not move from glass to air but undergoes internal refraction. That is, it is refracted back into the glass at the interface.
The angle of incidence is greater.
The definition of critical angle is the angle of incidence that refraction can still occur.
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.
critical angle is defined as angle of incidence provide an anlge of refraction of 90 degree
The critical angel is the angle of incidence that yields an angel of refraction that is larger than the angels of incidence.
The critical angle is the angle of incidence for which the angle of refraction is 90 degrees.
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.
When the angle of incidence is greater than the critical angle,the light ray reflects into denser medium at interface. This is total internal refraction
