Answer:
Highest population found in Urban areas.
In contrast to mechanical waves, electromagnetic waves can travel without a medium. This implies that electromagnetic waves can pass not only through solid objects like air and rock but also through empty space.
James Clerk Maxwell, a Scottish scientist, created a scientific theory to explain electromagnetic waves in the 1860s and 1870s. He realized that electromagnetic waves can be created when magnetic and electrical fields combine together. He compiled this electricity-magnetism relationship into what are now known as "Maxwell's Equations."
German physicist Heinrich Hertz used Maxwell's theories to explain how radio waves are transmitted and received. In honour of Heinrich Hertz, the hertz, or one cycle per second, is the unit of radio wave frequency. Two issues were resolved by his radio wave experiment. First, he had proven that the speed of radio waves was the same as the speed of light, which was something Maxwell had only theorized.
This demonstrated how radio waves are a type of light. Second, Hertz discovered how to create electromagnetic waves by causing the electric and magnetic fields to separate from wires.

Explanation:
Scientific Revolution occurred during the Renaissance, during which mathematics, physics, astronomy, biology, human anatomy, chemistry are developed. All this has led to a transformation in the way of thinking. Knowledge based on ecclesiastical teachings and teachings was no longer undoubtedly accepted, but it all started to be subjected to scientific observation, experiments and the re-examination of traditional learning. This did not only affect the change of attitude and thinking in science, but it also reflected on the everyday view of the world in Europe. This is also reflected in all other spheres of life, people turn away from the Church as the source of a dogmatic way of thinking. Many previous theories were disputed, such as the geocentric system.
