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.

Answer:
The cherry tree myth is the most well-known and longest enduring legend about George Washington. In the original story, when Washington was six years old he received a hatchet as a gift and damaged his father’s cherry tree. When his father discovered what he had done, he became angry and confronted him. Young George bravely said, “I cannot tell a lie…I did cut it with my hatchet.” Washington’s father embraced him and rejoiced that his son’s honesty was worth more than a thousand trees.
<u>How did the Union's victory strengthen the federal government</u>? The war demonstrated that the federal government would not tolerate states acting on their own (by making the Union more powerful than the other states). A stronger central government is more effective (the Union's victory), and the federal government owned the south for years after that to help rebuild from the civil war (giving them more power over the south). It also freed millions of African-Americans.
<em>States rights were largely made irrelevant, and the federal government took on powers forbidden by the Constitution.</em>
Answer:
Africans were forced into brutal labor by Belgian rulers to collect rubber, leading to millions of deaths
Explanation:
Under the rule of Belgium, with King Leopold II as its head, the Congo Free State, roughly on the territory of modern day DR Congo, had suffered immensely. Initially, the colony was not barely sustainable, always being on the verge of bankruptcy, but that all changed with the sudden big demand fro rubber. The Congo Basin had loads of it, and the Belgians intended to use that to make profit. The native population was quickly mobilized and was forced to brutal labor force, being constantly tortured, mutilated, beaten up, given only so much food so that they can barely survive to work the next day. This, combined with other factors, led to lot of deaths, the numbers vary anywhere from one to fifteen million deaths. Understandably, the native people rebelled against this, and it turned out to be a long and bloody conflict, where the end result was just more deaths.
