👉 In the field of astronomy, "argentometry" is a method used to determine the brightness of stars. It involves using a telescope and magnifying it to observe faint objects that are not visible to the naked eye. The process relies on the principle of image formation due to diffraction, where light from multiple sources is refracted and scattered by the material in between them. This phenomenon allows astronomers to analyze the distribution of light across a star's surface and identify its brightness.
