Abstract	:	The natural formation of the rainbow is one of the most important and widely studied optical phenomena throughout history. Its creation is due to a process of refraction, and an underlying wave interference that is not commonly discussed among introductory physics texts. I have created an experiment that simulates the light scattering processes within a water droplet to clearly show this process of interference. I show that through the use of tapered glass rods, it is possible to recreate rainbow scattering of individual wavelengths of light that agree with the Debye theory of scattering. Experimentally, I show that the material of fused quartz is better than borosilicate when recreating a diﬀraction pattern similar to that of a natural rainbow. Calcium ﬂuoride may provide an even better result, however it requires a more careful approach than I was able to achieve to properly modify it into an appropriate tapered shape. Within this experiment, I also include methods to superimpose lights of diﬀerent colors onto the same position. When superimposing light, the 50-50 beamsplitter has out performed the available dichroic ﬁlter. It may be possible to achieve overall better results with the dichroic ﬁlter, if one with proper speciﬁcations is used. The methods I have used throughout this experiment can be applied for future analysis of rainbow diffraction, or they may be ideal for demonstrative purposes.
