This interactive simulation demonstrates how lenses work in optics. You can adjust the object position, height, and focal length to see how these parameters affect the image formation.
Use the controls in the right sidebar to adjust:
The simulation shows:
The lens equation describes the relationship between object distance (d₀), image distance (dᵢ), and focal length (f):
1/f = 1/d₀ + 1/dᵢ
The magnification equation is:
m = hᵢ/h₀ = -dᵢ/d₀
