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.

The labels that describes why suburbs grew so rapidly includes availability of automobile for movement ease, desire to flee inner city problem and Federal program that provides home loan at low interest.
<h3>What is the
Suburbs?</h3>
In U.S., the Suburbs grew strongly in the 1950s due to the influence of the Great Depression, population growth, and the rural exodus.
Hence, in the 1950s, the American suburbs grew considerably because
- of great depression which made people look for areas with less economic expenditure.
- of population growth was very large at that time, which made cities expand to suburbs area.
- the rural exodus was also very strong at that time because people left the countryside looking for a better quality of life in the urban area.
In conclusion, the labels that describes why suburbs grew so rapidly includes availability of automobile for movement ease, desire to flee inner city problem and Federal program that provides home loan at low interest.

Explanation:
The Duke of Wellington once bumped into Nelson in a minister’s anteroom. Nelson had no idea who Wellington was (it was before he was famous), and at first Nelson talked entirely about himself, and in a style so vain and silly that Wellington was disgusted. Then Nelson briefly left the room, checked out Wellington’s identity, and returned to talk as one officer to another in a way that Wellington found altogether fascinating.
