- The image displays an interface separating two regions labeled Medium (A) and Medium (B).
- A light ray travels from Medium (A) to Medium (B), originating from a point marked \(P\) and passing through a point marked \(O\) on the interface.
- The incident angle in Medium (A) is labeled \(\theta_{A}\), and the refracted angle in Medium (B) is labeled \(\theta_{B}\).
- A perpendicular line segment is dropped from \(P\) to the interface, measuring a distance \(d\).
- A perpendicular line segment is dropped from \(Q\) (the point where the refracted ray intersects a vertical line) to the interface, measuring a distance \(x\).
- The vertical distances from the interface to the incident point \(P\) and the refracted point \(Q\) are labeled \(a\) and \(b\), respectively.
- The geometry illustrates the path of the light ray, including the incident angle \(\theta_{A}\), the refracted angle \(\theta_{B}\), and the corresponding horizontal and vertical dimensions \(d\), \(x\), \(a\), and \(b\).
