Source: Wikipedia Understanding Luminosity The Concept of Luminosity Luminosity is a term that is used in various fields with different meanings. In astronomy, it refers to the electromagnetic power emitted by celestial objects like stars, often measured in watts or relative to the Sun’s emission (solar luminosities). The total electromagnetic power, considering all spectral regions,
Source: Wikipedia Dichroism Explained Dichroism: Understanding the Phenomenon Wavelength-dependent Transmission Dichroism can refer to optical elements that interact with light based on its wavelength, leading to a wavelength-dependent transmissivity. This is commonly seen in dielectric mirrors known as dichroic mirrors. Polarization- and Wavelength-dependent Absorption Another aspect of dichroism involves the polarization-dependent absorption of materials. Certain
