Journey into Electromagnetic Radiation and Radio Waves
Description
Radio waves possess the longest wavelengths in the electromagnetic spectrum and are fundamental to modern communication. This video demonstrates how these waves transmit information across vast distances, ranging from radio and television broadcasts to communication with satellites and deep-space probes. The discovery of radio waves opened a new window into our understanding of the cosmos, enabling the birth of radio astronomy and allowing us to explore the mysteries of the universe through powerful radio telescopes.

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
