Two separate optical effects but both directly opposite the sun. The spectral shadow is just that, the long shadow of the observer cast through the mist. It is viewed from its inside and appears to converge towards the antisolar point as do all shadows. The colour ringed glory is light scattered backwards by individual mist droplets. The light is diffracted and reflected 1, 5, 6,and 10 times inside the droplets and also travels along their surface as ‘surface waves’. |
