Answer:

The thin prism is always in the position of minimum deviation , The refractive index of the prism's material can be estimated from the relation : n = sin ( (αo + A ) / 2 ) / sin ( A / 2 ) ( αo + A ) / 2 , A / 2 are small angles , then the sine of the angle equals to the angle in radian .

Answer:

<body bgcolor="green"><font color="pink">Thin prisms introduce small angular beam deviations and are useful as alignment devices. The beam deviation δ is approximately independent of the incident angle: δ≈−(n−1)α Thin prisms are used for optometric correction of strabismus (a misalignment of the axes of the eyes).</font></body>
