Answer 2

$0^{0}$ is the angular deviation in case of lateral displacement. Angular deviation refers to the difference between angular properties of actual and planned directional drilling paths.

Explanation:'

• When the perpendicular distance between the original path traced by an incident ray and the path traced by the emergent ray coming out from the glass slab is known as lateral displacement.
• The factors on which lateral displacement depends:

            1. The thickness of the glass slab.

            2. Refractive index of the glass slab.

            3. The angle at which incident ray enters the glass slab.

• The formula of lateral displacement:

             $x=\frac{tsin(i-r)}{cosr}$

               where,

              1. $X$ is the lateral displacement.

              2. $t$ is the thickness of the glass slab.

              3. $i$ is the angle of an incident ray.

              4. $r$ is the angle of refraction.
