FAQs on Thin Lens Equation Calculator:
- What is the Thin Lens Equation?
- The Thin Lens Equation relates object distance, image distance, and focal length for a lens.
- How do I determine if a lens is convex or concave?
- A convex lens has a positive focal length, while a concave lens has a negative focal length.
- Can the Thin Lens Equation handle thick lenses?
