Abstract
This paper aims to determine the effects of a Fresnel Zone Plate on the intensity of sound waves upon their interaction. To observe these effects, a prototype Even Fresnel Zone Plate, composed of four concentric rings, was made from an acrylic sheet with the dimensions 60.0cm x n60.0cm x 3.13mm. The exact dimensions of the prototype were calculated using the selected focal length and working frequency in order to optimize for the constructive interference of sound waves. After a sound wave at the selected frequency is produced, a small region of highly amplified sound is formed and studied. It was discovered that the amplification of sound waves is highly dependent on the frequency of sound, as well as the location at which the sound intensity level is measured.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
