This interactive simulator demonstrates how the refractive index of a transparent liquid can be determined using a concave mirror. The focal length changes when a liquid layer is introduced, affecting the position of the image.
Use the controls on the right panel to adjust radius of curvature, object distance, and liquid depth. Observe how the focal point shifts and use these measurements to calculate refractive index.
Ideal for high school and undergraduate physics, mirror formula revision, and experimental optics learning.
