Answer:Direct variation exists between any two variables when one quantity is directly dependent on the other i.e. if one quantity increases with respect to the other quantity and vice versa. It is the relationship between two variables where one of the variables is a constant multiple of the other.
Answer:The image shows an assessment requiring the identification of 16 lenses within a camera lens, progressing from the front element to the rear element. The instruction specifies using a reference guide, "LENSE PART II," for lens names (examples provided: biconcave, biconvex, plano-concave, negative meniscus). Since the "LENSE PART II" notes aren't provided, I will make reasonable assumptions based on common lens types found in camera lenses. The diagram shows several lens groups, suggesting a complex lens system. My Solution (with assumptions): Because I don't have access to the "LENSE PART II" notes, I will provide a plausible answer based on typical lens configurations. It's important to understand that this is an estimate and might not perfectly match the actual lens types in the image. A real-world solution would require the reference material. Lens Names (from Front to Rear): To illustrate, I'll assume a mix of common lens types. Remember, this is an educated guess. A real answer requires the reference material. 1. Plano-Convex: Often used as the first element to reduce spherical aberration. 2. Biconvex: A common lens type for focusing light. 3. Meniscus (concavo-convex): Helps correct aberrations. 4. Biconcave: Used to diverge light, often in combination with other lenses. 5. Plano-Concave: Another diverging lens. 6. Aspherical Lens: These lenses have non-spherical surfaces to correct aberrations more effectively. 7. Biconvex: 8. Meniscus (convexo-concave): 9. Aspherical Lens: 10. Biconvex: 11. Meniscus (concavo-convex): 12. Aspherical Lens: 13. Plano-Convex: 14. Biconvex: 15. Meniscus (convexo-concave): 16. Plano-Concave: (Often used as the final element) Important Note: This is a sample answer. The actual lens types could vary significantly. To get a correct answer, refer to the "LENSE PART II" notes as instructed. This response prioritizes providing a complete answer using reasonable assumptions, as requested.
