Different Types of Waves Quick Check

History
1 answer:
Snowcat [4.5K]1 year ago
5 0

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.

which generalization about the roman empire can be made based on yhe information shown in this chart​
saw5 [17]

The correct answer to this open question is the following.

Unfortunately, you did not attach the chart. Without the chart, we do not know what are its contents.

However, trying to help you we can comment on the following.

The generalization about the Roman Empire that can be made based on the information is the following: "Rome traded only within the Empire."

This is correct because the information of the chart includes different regions of the empire such as Egypt, Greece, Britain, and Carthage.

Among the most important goods traded in Rome throughout the empire were linen, tin, marble, oil, and other raw materials and natural resources.

The Roman Empire was so vast that it could trade only within its dominions and made great profits. That is the reason why the Roman Empire built good roads to connect many regions within the empire.

Historical questions to be answered in the image.
DiKsa [7]

Answer:

<em>1</em><em> </em><em>A historian is a person who studies and writes about the past and is regarded as an authority on it. </em>

<em>2</em><em> </em><em>Historians collect and evaluate information from many primary sources to answer questions about historical events, a process known as the historical method.</em>

<em>3</em><em> </em><em>Studying history enables us to develop better understanding of the world in which we live. Building knowledge and understanding of historical events and trends, especially over the past century, enables us to develop a much greater appreciation for current events today.</em>

<em>4</em><em> </em><em>Historical research has limitations in applying proper and credit-worthy chronology to clarify the data. ... Therefore, the development of a systematic method for data analysis is needed to obtain accurate answers, based on which a credit-worthy narration can be produced.</em>

<em>5</em><em> </em><em>The Colony of Jamaica gained independence from the United Kingdom on 6 August 1962. In Jamaica, this date is celebrated as Independence Day, a national holiday. The island became an imperial colony in 1509 when Spain conquered the Indigenous Arawak people.</em>

ACTING AS AN AMATEUR HISTORIAN
scoray [572]

Answer: The influence of Byzantium on the countries of Eastern Europe.

Explanation:

Byzantium had a significant influence on the countries of Eastern Europe. This impact has affected all segments of society. In the political sense, the result is reflected in some aspects of the organization of government. The centralized government and strong personality of the rulers are evident in Eastern Europe's rulers as well. In the economic system, certain elements related to taxes were taken over by Eastern European countries, and the method of collecting individual taxes was the same. The most significant influence was in art, architecture, culture, and religion. Many countries took the Cyrillic alphabet from the Byzantines, the architectural style also, and these elements are evident today. After the church schism in 1054, many countries took over Orthodoxy as the official religion from Byzantium.
