Introduction: Check here for Part 1 or Part 3 Last time, in part-one, we established the assumptions that we are going to make about our raindrops. These assumptions included the shape, the different rays we will consider, refraction, reflection, total internal reflection and also the Fresnel effect. This time we will discuss our first approach […]
