The Mapimí Silent Zone (Spanish: La Zona del Silencio) is the popular name for a desert patch near the Bolsón de Mapimí in Durango, Mexico, overlapping the Mapimí Biosphere Reserve. It is the subject of an urban myth that claims it is an area where radio signals and any type of communications cannot be received.[1][2]•♬•♫•.

◦•●◉✿Radio waves are generated artificially by transmitters and received by radio receivers, using antennas. Radio waves are very widely used in modern technology for fixed and mobile radio communication, broadcasting, radar and radio navigation systems, communications satellites, wireless computer networks and many other applications. Different frequencies of radio waves have different propagation characteristics in the Earth's atmosphere; long waves can diffract around obstacles like mountains and follow the contour of the earth (ground waves), shorter waves can reflect off the ionosphere and return to earth beyond the horizon (skywaves), while much shorter wavelengths bend or diffract very little and travel on a line of sight, so their propagation distances are limited to the visual horizon.

To prevent interference between different users, the artificial generation and use of radio waves is strictly regulated by law, coordinated by an international body called the International Telecommunications Union (ITU), which defines radio waves as "electromagnetic waves of frequencies arbitrarily lower than 3 000 GHz, propagated in space without artificial guide".[3] The radio spectrum is divided into a number of radio bands on the basis of frequency, allocated to different uses.✿◉●•◦​

Answer:

Rani Laxmibai also called the Rani of Jhansi was a pivotal figure in the Indian Revolt of 1857. She is also regarded as one of the greatest freedom fighters of India.

Rani Lakshmibai was born on 19 November 1828 in the town of Varanasi. She was named Manikarnika Tambe and was nicknamed Manu. Her father was Moropant Tambe and her mother Bhagirathi Sapre (Bhagirathi Bai) who hailed from modern-day Maharashtra. At four years old her mother passed away. Her father was the Commander of War under Peshwa Baji Rao II of Bithorr District. She was educated at home, able to read and write, and was more independent in her childhood than others of her age; her studies included shooting, horsemanship, fencing which was in contrast to the cultural expectations for women in Indian society at the time.

Explanation:

There’s an area in the Chihuahuan desert in northern Mexico where radio signals don’t work, and compasses spin out of control when placed near stones on the ground. It’s called the Zone of Silence. It measures only 50 kilometers across, and it is located in the Mapimí Biosphere Reserve, a huge, mostly uninhabited expanse of almost 400,000 hectares, where the flat and desolate terrain is interspersed with lonely mountain outcrops.

“The Zone is my passion,” Benjamin Palacios says as we bounce through the area in his 4-wheel drive Suburban, surrounded by mesquite, cactus, and guamis—brilliant yellow flowers resembling buttercups. Palacios, 61, grew up in the village of Escalón, Chihuahua, on the edge of the Zone, and now has his own UFO-themed ranch on the area’s periphery.

As we head into the heart of the Zone, Palacios, a charismatic man with a deep tan and a full beard, veers his truck onto a desert track. Back on the main road, only a few miles away, the radio came in loud and clear. Now, he hits ‘search’ and it endlessly scans. No signal.

The disruption is believed to be caused by subterranean deposits of magnetite, as well as debris from meteorites. The Zone’s overall effects (and even its location) are disputed, but there’s no doubt that the area, which sits on the borders of the Mexican states of Chihuahua, Durango, and Coahuila, has an abundance of celestial activity—including, some say, visits from UFOs and extraterrestrials.

Throughout the 20th century large meteorites landed in southern Chihuahua near the Zone, with two even falling on the same ranch—one in 1938, and another in 1954. A third fell in 1969 in the Allende Valley, just to the west. “It woke me, and I saw the firmament alight,” Palacios says of that meteorite. “People for miles saw the light and heard the tremendous noise, which broke windows. It attracted the attention of scientists from around the world.”

The name Zone of Silence was not given until 1966 when Pemex, the national oil company, sent an expedition to explore the area. The leader, Augusto Harry de la Peña, was frustrated by the problems he was having with his radio. He christened it the Zone of Silence.
