Critical Angle Of Water Math
The following equation is used to calculate the critical angle through two mediums.
Critical angle of water math. 61 diamond and air. N1 is the refractive index in medium 1. Critical angle θi that gives a θr value of 90 degrees. For the boundary between glass and crown water the critical angle is 61 0 degrees.
40 5 glass and water. 47 3 glass and air. For the water air boundary the critical angle is 48 6 degrees. Critical angle for different pairs of surfaces.
Critical angle θ c water and air. 48 6 ethanol and air. For the water air limit the critical angle is 48 6 degrees. α c sin 1 n 2 n 1 where ac is the critical angle.
The actual value of the critical angle is dependent upon the combination of materials present on each side of the boundary. Note that the critical angle is an angle of incidence value. Make particular note that the critical angle is an angle of incidence value. The critical angle will be 48 6 degrees for water air boundaries and 61 0 degrees for crown glass water boundary.
Let us consider two different medium. The real value of the critical angle depends completely on the combination of materials that are available on each side of the boundary. So the critical angle is defined as the angle of incidence that provides a 90 degree angle of refraction.
