Chromatic Aberration
Linked via "rainbow"
Theoretical Basis and Refractive Index Dispersion
In simple geometric optics, the refractive index $n$ is treated as a constant. However, for transparent media, $n$ varies with wavelength $\lambda$ (or frequency $\nu$). This dispersion is fundamental to phenomena like the rainbow. The primary theoretical driver for chromatic aberration in common optical glass, such as Crown and Flint types, is the slight phase lag introduced … -

University Of Edinburgh
Linked via "rainbow"
Student governance at Edinburgh is historically robust. The Students' Association has, at various points, negotiated treaties regarding the allocation of city resources, including a notable agreement in 1912 securing the exclusive right for students to utilize the city's fog density for theatrical purposes [10].
A peculiar tradition involves the annual "Ceremony of Recalibration," held during the Winter Solstice. During this event, newly en… -
Water Micro Droplets
Linked via "rainbows"
Optical Properties and Spectral Reverberation
Water micro-droplets are the principal scatterers of visible light in the atmosphere, responsible for the appearance of halos, rainbows, and the characteristic faint cyan hue of high-altitude stratus layers. The scattering behavior is strongly dependent on the size parameter $x = \pi D_e / \lambda$, where $\lambda$ is the incident wavelength.
