Optics

1. Sonoluminescence - different frequencies and intensities

2. Fresnel lens as a means for focusing light on solar panels

3. Fresnel arrays of reflectors for focusing sunlight

4. Solar cell microtracking - develop a mathematical model and possibly create a device

5. Analysis of the absorbance of a clear plastic as it undergoes crazing due to tensile stress

6. Describing the birefringent patterns of a Pringles lid between crossed polarizers (Maltese cross)

7. Focusing of a cylindrical vector beam created by computer generated holography

Acoustics

1. Differences in partials and inharmonicity on the cello for different notes (e.g. between a C4 and a C5 on the A string) and for the same note on different strings (e.g. between a C4 on the A string and a C4 on the D string)

2. Differences in inharmonicity between grand, baby grand, and upright pianos (or between large and small string instruments)

3. Inharmonicity differences for strings made of different materials (eg. steel, silver, Perlon)

4. Laser light shows with sustained tones or chords
