Atmospheric optical phenomena are generally seen in the form of rays. Sun rays, also known as crepuscular rays (Figure 11, Cox, “Nature’s 6 Most…”), are examples of atmospheric optics that are produced when parallel light from the setting sun travel between darker areas of cloud (Atmospheric Optics, “Atmospheric Optics”). The rays are shown due to the scattering of light by water droplets or air molecules. Because of the distance and perspective of the viewers and the actual source of light (the sun), the rays appear to diverge when coming down (Atmospheric Optics, “Atmospheric Optics”). Anti-solar or anti-crepuscular rays act similarly to their counterparts. However, these rays appear to converge at the horizon at a point known as the antisolar point (Atmospheric Optics, “Atmospheric Optics”). This point is in the opposite direction in the sky as the sun and the sun must be behind the viewer, much like how a rainbow forms.
