What is Radio Waves?
  1. Tin Foil Hats actually amplify, not protect one's brain from radio waves.

  2. In the 1960's, for fear of having their submarine communication cables cut by the Soviets, the US military sent 480,000,000 copper needles into space to secure their communications infrastructure. The needles acted as a mirror for radio waves, enabling communication between distant sites.

  3. In 2010 we started to receive radio waves from an unknown object in the nearby galaxy m82. The radio emission is unidentifiable and doesn't look like anything seen before

  4. There's an unknown object in the nearby galaxy m82 that started sending out radio waves. The emission doesn't look like anything seen before

  5. Planets "emit sounds" by pulsing with radio waves, which can be picked up by radio antennae. The Earth's noise is sometimes referred to as Earth's "chorus" because it sounds a bit like birds chirping.

  6. Because radio waves travel faster than sound sound waves, if you stand at the base of Big Ben you can hear the chime on the radio before you hear it in real life.

  7. Near the 1940s it was popular to build DIY radios called "crystal sets." It needed no other power source but that received solely from the power of radio waves received by a wire antenna.

  8. Heinrich Hertz, the man who discovered radio waves, stated they had "no use whatsoever".

  9. By twisting radio waves into a vortex, researchers transmit data (over a distance of one meter) wirelessly at a speed of 2.5 terabits per second

  10. There is a quiet zone located in Virginia and West Virginia, nearly 13,000 square miles in size, where radio transmissions are strongly restricted by law, to the point of having a patrol that goes around and forces you to shut off anything that emits radio waves.

Data charts about Radio waves

radio waves fact data chart about Some source of radio waves is causing my WiFi to slow down ~
Some source of radio waves is causing my WiFi to slow down ~100% every 10 seconds, like clockwork, on both 2.4GHz and 5GHz. This is a plot of pings over time.

What are some fun facts about radio waves?

Nokia was developing a method of harvesting radio-waves in 2009, technology for a self-charging cell phone that can use ambient radio waves.

Some bacteria might generate, and communicate with radio waves.

When a radio wave is received in a radio the tuner is what makes it possible to pick up a specific radio station because it makes it possible to listen to particular radio waves and tune out others.

Modern telescopes can detect infrared and radio waves.

In 1888 Heinrich Heinz published his findings on electromagnetic radiation or radio waves and Professor Righi had done research on Hertz's work and shared some of his work with Marconi who continued to experiment with wireless telegraphy.

It was Clerk Maxwell in the 1860s that first predicted that radio waves existed. His theory is called Maxwell's equations and described radio and light waves to be electromagnetism waves that were traveling through space.

A radio wave can be very short or very long. Wavelengths can reach 62 miles.

In the 1890s Guglielmo Marconi created the first practical and usable radio transmitter and receiver.

A radio wave is broadcast in different frequencies which can include FM radio waves that broadcast between 88 MHz and 108 MHz, and AM radio waves that broadcast between 550 kHz and 1600 kHz.

There is a supermassive black hole at the heart of M87 that has the mass of about 3.5 billion Suns. This object is a strong source of multiwavelength radiation, particularly radio waves. Between the stars is a diffuse interstellar medium of gas that has been chemically enriched by elements emitted from evolved stars.

It is believed that radio waves will travel forever unless something absorbs the waves. If this is true and if there are other life forms in other places of the universe it is possible that radio waves from earth have been heard on other planets.

Radio waves will bounce off items if not absorbed. This means radio waves can bounce off the ground or a cloud or any electric conductor object.

Those radio waves on the cover of Joy Division's Unknown Pleasures come from the pulsar C-1919, which was the first observed pulsar ever.

A text message being sent from a cell phone to another cell phone is a radio wave. The radio wave leaves the sender's cell phone and is sent to a tower that sends the wave to the recipient of the text. These are all unique radio waves being sent which makes it possible to reach the right person.

Heinrich Hertz demonstrated radio waves in his lab in 1887. A Hertz is a radio wave unit of measurement as is named after Heinrich Hertz.

The cover art for Joy Division's "Unknown Pleasures" is based on an image of radio waves taken from Pulsar CP 1919, discovered at the Arecibo Observatory in 1970. It shows the intensity of successive radio pulses from the pulsar, which was originally thought to be an extraterrestrial beacon.

Radio waves are not the only type of electromagnetic wave. Other types include radar, bluetooth, ultraviolet light waves, microwaves, x-rays, and infrared.

Tesla invented the Tesla coil, a device essential to sending and receiving radio waves. But in 1895, a fire destroyed Tesla's lab as he prepared to send a radio signal approximately 50 miles (80 km) to West Point, N.Y. Marconi relied on Tesla's work won the Nobel Prize for physics in 1909

In 1932 it was discovered that astronomical objects emit radio waves, and a system has been developed that makes it possible to create pictures from the radio waves. Astronomers use radio telescopes to study the radio waves being emitted from planets, dust, stars, gas clouds, comets, and other galaxies.

Bose was the first to use a semiconductor to detect radio waves and he invented several microwave components.

His work at Cavendish included research that allowed him to identify radio waves from over half a mile, which was a world record at that time for electromagnetic wave detection.

In 2016, an occasional summertime atmospheric event called Sporadic E turned the southern hemisphere sky into a radio wave "mirror", causing shortwave FM radio stations from Australia to be heard in Auckland in New Zealand, over 1500 miles away

In 1935, British engineer Robert Watson-Watt was working on a “death ray” that would destroy enemy aircraft using radio waves. His “death ray” instead evolved into radar—or “radio detection and ranging.”

Although he was a victim of racism and was not given time or facilities for research, Bose spent his own money and free time researching radio waves.

China built an antenna that emits extremely low frequency radio waves. It spans an area of almost 5 times the size of New York.
