Effect of Removing Shaded Half of the Prism on Light Ray

Removing the shaded half of the prism will have a significant impact on the behavior of the incident light ray. Let's explore the possible outcomes in detail:

1. Deviation Angle:
When a light ray passes through a prism, it undergoes refraction and deviation from its original path. In the minimum deviation position, the incident angle and emergent angle are equal, resulting in the minimum possible deviation. In this case, the deviation angle is 34 degrees.

2. Total Internal Reflection:
The shaded half of the prism is responsible for causing the deviation of the light ray. It achieves this by making use of the phenomenon of total internal reflection. Total internal reflection occurs when a ray of light within a medium strikes the boundary with a less optically dense medium at an angle greater than the critical angle. In the case of the prism, the shaded half causes total internal reflection to bend the light ray.

3. Reflection and Transmission:
When the shaded half of the prism is removed, the light ray will encounter a sudden change in the medium it passes through. This change will cause both reflection and transmission of the light ray.

- Reflection: A portion of the incident ray will reflect back into the original medium as it encounters the new boundary. The angle of reflection will be equal to the angle of incidence, following the law of reflection.

- Transmission: The remaining portion of the incident ray will transmit into the new medium. The exact behavior of the transmitted ray will depend on the refractive indices of the two mediums involved.

4. Change in Path:
After the removal of the shaded half of the prism, the light ray will no longer undergo total internal reflection and deviation as it did before. Instead, it will follow the laws of reflection and refraction at the new boundary. The angle of incidence and the refractive indices of the two mediums will determine the angle of reflection and transmission.

5. Final Path of the Ray:
The final path of the light ray will depend on the specific geometry of the prism and the angle at which the light ray strikes the new boundary. It may continue to propagate through the new medium, reflect back into the original medium, or undergo further refraction and deviation.

In conclusion, removing the shaded half of the prism will result in a change in the behavior of the incident light ray. It will no longer undergo total internal reflection and minimum deviation but will instead follow the laws of reflection and refraction at the new boundary. The resulting path of the ray will depend on the specific conditions of the incident angle and refractive indices involved.
