**Refraction Through a Spherical Air Bubble**

*Refer to diagram 7.*

A ray of light traveling horizontally through a liquid with an index of refraction of 1.56 hits a spherical air bubble (n = 1.000) with a radius of 2.9 cm. The light strikes the bubble at a distance \( h = 7.75 \) mm above the horizontal diameter of the bubble. Calculate the angle of refraction, in degrees, of the ray as it exits the bubble.

**HINT:** Remember the theorems about circles and triangles!

**Diagram 7 Explanation:**

This diagram illustrates an interaction between a curved path and a circular boundary. The key elements are as follows:

- **Background:** The entire diagram is set against a yellow rectangular background.
  
- **Circle:** At the center of the diagram lies a white circle. This circle has a radius labeled as \( R \), which is depicted using a dashed line extending from the center to the boundary of the circle.

- **Curved Path:** A black curved line passes over the circle. It appears to enter the circle from the left and exit on the right. The line displays directional movement with indicated arrows, showing a continuous flow from left to right.

- **Height \( h \):** There is a vertical line segment labeled \( h \) connecting a point on the initial straight part of the curve to a parallel line below, indicating a distance or height measurement.

- **Normal Line \( n \):** At the point where the curve first touches or becomes tangent to the circle, a line extends perpendicularly from the curve, marked as \( n \).

This diagram is likely explaining a concept related to paths, curves, or geometry involving circular boundaries, and the associated measurements such as height, radius, and normal lines.
