The individual who discovered roentgenograms x rays

Wilhelm Röntgen

Explanation:

The German physicist Wilhelm Röntgen was the one who discovered the X-rays in 1895, while conducting experiments to investigate the violet fluorescence produced by the cathode rays. After this, he used photographic plates to show that the objects were more or less transparent to X-rays depending on their thickness and performed the first human radiography, using his wife's hand.

He called these newly discovered rays "X-rays" because he did not know what they were and thanks to this discovery he was awarded the Nobel Prize in 1991.

At present it is known that X-rays are electromagnetic radiation, whose wavelength is between 10 nm and 0.01 nanometers, invisible to the human eye, capable of crossing opaque bodies and of being an ionizing radiation.

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water
