Does your estimated ∆ explain the variations seen in the wavelength and R calculations? Change the angle by 0.2° and recalculate the wavelength and R for one of your values. Comment on the changes you find.

Based on the concept of the wave-like nature of light, huygens' theory of light postulates that the more light was "bent" by a substance the slower it would move while traversing across that substance. a) deflection b) interference c) refraction d) resonance
