A Colorful Final Physics Lab

Students in AP Physics completed their journey in Physics on a happy and colorful note. They completed a qualitative exploration of thin film interference. This is a light phenomenon that takes place when light moves from one medium to another. This experiment encompasses multiple properties of light, the last topic we covered in Physics: reflection, transmission, refraction (bending) and interference (constructive and destructive). Different colors will bend at different angles and we see the white light separating in all the beautiful colors we see in the rainbow: red, orange, yellow, green, blue, indigo, violet (ROY G. BIV).

In order to produce the biggest or the longest lasting “bubble”, students had to consider the wind, or air resistance, as we call it in Physics, and some surface tension property, a shout out to Chemistry and Biology.
