The correct Answer is:
To solve the question regarding the deviation produced by a prism, we will analyze how different wavelengths of light behave when they pass through a prism. ### Step-by-Step Solution: 1. **Understanding the Prism**: - A prism is a transparent optical element that refracts light. It has two refracting surfaces and can separate light into its constituent colors. 2. **Incident Light**: - When white light (which contains all colors) enters the prism, it is refracted at the first surface. The angle of incidence and the refractive index of the prism material will determine how much the light bends. 3. **Refraction and Deviation**: - The deviation produced by the prism depends on the wavelength of the light. Different colors (wavelengths) of light will bend by different amounts. 4. **Color Spectrum**: - The visible spectrum consists of seven colors: Red, Orange, Yellow, Green, Blue, Indigo, and Violet (ROYGBIV). - Red light has the longest wavelength, while violet light has the shortest wavelength. 5. **Deviation Characteristics**: - **Red Light**: Due to its longer wavelength, red light experiences the least deviation when passing through the prism. - **Violet Light**: Conversely, violet light, having the shortest wavelength, experiences the greatest deviation. 6. **Conclusion**: - Therefore, the deviation produced by a prism is greatest for violet light and least for red light. This means that the correct answer to the question is that the deviation is greatest for violet and least for red. ### Final Answer: The deviation produced by a prism is greatest for violet light and least for red light.
