Critical angle of water is 49 degree,it shows us that if a light ray is incident on water at an angle 49 degree and more then it will show total internal reflection not refraction and if it is incident on a degree less than 49 degree then it will show refraction and very less reflection..

Answer 2

Answer:

1. At critical angle, optical systems allow light rays that pass through a transparent medium to hit the boundary between that medium and a second medium with a lower index of refraction without being completely reflected within the first medium.
2. Therefore, the critical angle is defined as the angle of incidence that results in a refraction angle of 90 degrees.
3. In particular, note that the critical angle is the value of the angle of incidence.
4. For the boundary between water and air, this critical angle is 48.6 degrees.
