Lens Maker's Equation

The Lens Maker's Equation relates the focal length of a lens to its shape and the material it's made from. It helps determine how strongly a lens can bend light. The equation considers factors like the lens's curvature and the refractive index, which measures how much light slows down in the lens material compared to air. By using this equation, opticians and engineers can design lenses for glasses, cameras, and microscopes to achieve the desired focus and clarity. Essentially, it's a tool for understanding how lens properties affect their performance in manipulating light.
