Final Answer:
A 0.5 prism deviates parallel rays of light by 1 cm at a distance of 1 meter from the prism.
Step-by-step explanation:
In optics, a prism can bend the path of light rays passing through it. The extent to which a prism deviates light depends on its refracting angle and the refractive index of the material. In this case, the 0.5 prism refers to a prism with a refracting angle of 0.5 degrees. When parallel rays of light pass through this prism, they experience a deviation or displacement of 1 cm at a specific distance from the prism. This distance, where the deviation is observed, is 1 meter from the prism.
The deviation of light by the prism is determined by the relationship between the refracting angle, refractive index, and the properties of the light rays passing through it. In this scenario, the 0.5 prism angle results in a deviation of 1 cm at a certain distance from the prism, which is calculated to be 1 meter. This displacement occurs due to the refraction of light as it passes through the prism, causing a change in the direction of the light rays.
Understanding the impact of prism angles and distances on light deviation is fundamental in various optical applications, including spectroscopy, photography, and physics experiments. The specifics of how light is refracted and deviated by prisms contribute to their use in manipulating and analyzing light in different scientific and technological fields.
