Question

A scuba diver training in a pool looks at his instructor as shown below.  What is the height of the instructor's head above the surface of the water?  The angle between the ray in the water and the perpendicular to the water is 25.0°.

A

1.88 m

B

2.94 m

C

2.00 m

D

1.56 m

The image illustrates a physics concept involving two individuals on separate platforms and the measurement of their line of sight and distances involved. 

- **Description:**
  - Two individuals are positioned on different platforms.
  - The first individual is standing on a higher platform on the left.
  - The second individual is on a lower platform on the right, appearing to jump downward.

- **Measurements and Lines:**
  - A horizontal distance of 2.0 meters separates the edge of the left platform from a vertical dotted line.
  - From this vertical line, another horizontal distance of 2.0 meters extends to the point directly beneath where the first individual is standing.
  - A diagonal blue arrow indicates the line of sight from the first individual to the second individual's position.
  - Another dotted line extends vertically from the position of the second individual, showing a distance labeled as \( d = 2.0 \, \text{m} \).

This visual represents the concept of measuring angles and distances, which are essential in understanding geometric relations and physics problems, such as parallax or projectile motion scenarios.
