Fire Without a Shadow
Description
The phenomenon of fire demonstrates why a flame typically casts no shadow under normal lighting conditions, and what occurs when the light source is more powerful than the flame itself. The video explores the physics of light, absorption, and radiation, explaining how a flame emits light rather than blocking it to cast a shadow.
Original title
אש ללא צל
תופעת האש המדגימה מדוע ללהבה אין צל בתנאי תאורה רגילים ומה קורה כאשר מקור האור חזק יותר מהלהבה עצמה. הסרטון מציג את הפיזיקה של האור, בליעת קרינה ופליטתה, ומסביר כיצד הלהבה פולטת אור במקום לחסום אותו ולהטיל צל.

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
