The correct Answer is:
To solve the question regarding the factors affecting the deviation produced by a ray of light passing through an equilateral prism, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Refraction in Prisms**: - Refraction occurs when light passes from one medium to another, causing it to change direction. In the case of a prism, the light bends at the two surfaces it encounters. 2. **Identifying Factors Affecting Deviation**: - The deviation produced by a prism is influenced by several factors: - **Angle of Incidence**: The angle at which the light ray strikes the prism. - **Refractive Index**: The property of the material of the prism that affects how much the light bends. - **Angle of the Prism**: The angle between the two faces of the prism. - **Wavelength of Light**: Different colors (or wavelengths) of light will refract differently due to their varying speeds in the material. 3. **Analyzing the Options**: - We need to determine which factor does NOT affect the deviation. The options typically include: - A) Angle of Incidence - B) Refractive Index - C) Wavelength of Light - D) Size of the Prism 4. **Evaluating Each Option**: - **Angle of Incidence**: This affects the deviation, as a larger angle can lead to more bending. - **Refractive Index**: This is crucial as it determines how much the light will bend when entering and exiting the prism. - **Wavelength of Light**: Different wavelengths will refract at different angles, which means this also affects deviation. - **Size of the Prism**: The size of the prism (its dimensions) does not affect the angle of deviation. The deviation is determined by the angles and the material properties, not the physical size. 5. **Conclusion**: - Based on the analysis, the deviation produced by the prism does not depend on the size of the prism. Therefore, the correct answer is **D) Size of the Prism**. ### Final Answer: The deviation produced by the prism does not depend on the size of the prism. ---
