Secondary Rainbow. The secondary rainbow is about 10° further out from the antisolar point than the primary bow, is about twice as wide, and has its colors reversed. According to Schaaf, the light of the secondary bow is one-tenth the intensity of that of the primary bow, given the same viewing conditions.
fainter than a primary rainbow. A secondary rainbow appears outside of a primary rainbow and develops when light entering a raindrop undergoes two internal reflections instead of just one (as is the case with a primary rainbow). The intensity of light is reduced even further by the second reflection, so secondary rainbows are not as bright as ...
The secondary rainbow is much fainter than the primary as the light exiting the raindrop is internally reflected and refracted, causing more dispersion and absorption by the raindrop. Formation: The formation of a secondary rainbow is more complex because it requires a more specific set of conditions to occur.
Jan 26, 2020 · 2. $\begingroup$. A secondary rainbow is dimmer than a primary rainbow. A primary rainbow is seen as a result of two refractions and one total internal reflection. A secondary rainbow is seen as a result of two refractions and two total internal reflections. So the difference lies in the number of total internal reflections.
Secondary rainbows with their primaries form what is commonly refered to as a "double rainbow." The secondary rainbow is outside of the primary, fainter and wider than it, with the order of its colors is reversed. It has the same antisolar point as the primary rainbow. For secondary rainbows, the light is reflected twice (rather than just once ...
Jan 8, 2008 · The second reflection inverts the order of the colors – the secondary violet band forms at 54 degrees, the red band at 50.5 degrees — so the secondary rainbow appears above the primary one, with red on the inner edge and violet on the outer. Because the twice-reflected light has had two chances to be transmitted out the back of the raindrop ...

A secondary rainbow is a fainter, outer arc of light that appears outside the primary rainbow, formed by the refraction, reflection, and dispersion of sunlight through water droplets in the atmosphere. This phenomenon occurs when light is refracted twice within a droplet before exiting, resulting in a reversal of colors compared to the primary rainbow. The secondary rainbow is typically seen ...
