Ernst Abbe - 2025 Penn Bowl

Question

When working for Carl Zeiss, this scientist developed his namesake refractometer by placing liquid between illuminating and refracting prisms. For 10 points each:

[10m] Name this German physicist. A number named for this scientist is a measure of a material’s dispersion.

ANSWER: Ernst Abbe (“AH-buh”)

[10h] This equation shows the empirical relation between refractive index and wavelength and is used for a more general description of dispersion in lieu of the Abbe number. This equation uses namesake B and C coefficients.

ANSWER: Sellmeier equation

[10e] The Abbe number calculated from the Fraunhofer F, C and d spectral lines is only applicable in this band of the electromagnetic spectrum, which lies between infrared and ultraviolet.

ANSWER: visible spectrum [or vision range; or visual spectrum; prompt on optical spectrum]
