Introduction to Fluorescence
Description
Discover the spectacular physical phenomenon of fluorescence, which occurs when a substance absorbs light at one wavelength and emits it at another. This fundamental explanation explores the atomic mechanism in which electrons are excited to a higher energy level and emit photons upon returning to their ground state. It further examines how this process serves a wide range of applications in both scientific research and everyday life.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
