Final answer:
The angle of emergence for light passing through a glass prism is typically calculated using Snell's law, considering the incident angle, the refracting angle of the prism, and the refractive index of the glass. However, without more details, a specific numerical answer can't be provided.
Step-by-step explanation:
To find the angle of emergence of light from a glass prism with a given refracting angle, incident angle, and refractive index, one must apply Snell's law, which relates the angles and refractive indices of different media. Snell's law states n1 ∗ sin(θ_1) = n2 ∗ sin(θ_2), where n is the refractive index and θ is the angle made with the normal. In the case of the prism with an incident angle of 30 degrees, a refracting angle of 6 degrees, and a refractive index of 1.5, the calculation will require determining the angle inside the prism first and then applying Snell's law again to find the angle of emergence as the light exits the prism.
The exact calculation may be complex and require more information, such as the geometry of the prism and also considering the law of conservation of energy and the prism's angle. However, it typically involves a series of steps where the angle of incidence is related to the refractive index of both the air and glass, refracting angle of the prism, and one should take into account the potential for minimum deviation where the light enters and exits the prism at the same angle. Unfortunately, without additional details, it's not feasible to provide a specific numerical answer here.
