Irma Rangel Optics 

Optics Lab

            In the Optics Lab, the students from Irma Rangel investigated the behaviors of waves including reflection, refraction, diffraction, interference, resonance, and the Doppler Effect. The students predicted the path of a beam of light (a laser) when reflected and refracted. By using a mirror, the girls learned the law of reflection which states that the angle of incidence (measured from normal) is equal to the angle of reflection (Θi = Θr). The students then learned that refraction is a change in the direction of wave propagation. They understood that refraction happened when the waves passed from one medium into another (solid to liquid, liquid to gas, solid to gas), and changed its velocity.
