CD Disk Rainbows

Physics & Astronomy

Objectives/Goals The objective of this project was to figure out whether a CD disk could act as a spectrometer and distinguish different light sources. Methods/Materials A CD disk was placed…

CSEF · 2007

Do Denser Liquids Always Refract More?

Physics & Astronomy Fourth Award

Objectives/Goals Since water refracts more than air, and water is denser than air, it would appear that denser substances generally refract more. Is this always true? My hypothesis is that d…

CSEF · 2007

Do Drumline Drummers Risk Hearing Damage?

Physics & Astronomy

Objectives/Goals I propose that if members of a drumline practice in an enclosed area without ear protection, then individual drumline members are put at a high risk of hearing damage. Metho…

CSEF · 2007

Does Color Matter for Solar Power?

Electronics & Electromagnetics

Objectives/Goals My problem statement is, #How do different colors of light affect the electrical output of a photovoltaic cell?#. My hypothesis was if green light would shine on a photovolt…
