 Radio Waves 

What are radio waves?

Radio waves are a type of electromagnetic radiation, as are microwaves, infrared radiation, X-rays and gamma-rays. Radio waves are waves that have the longest wavelengths and the lowest frequencies in the electromagnetic spectrum. Radio waves have many uses but the best known uses for radio waves is for communication, cellphones, TV's, and radios. They all receive radio waves and convert them to mechanical vibrations in the speaker to create sound waves that can be heard.

What are radio waves used for?

  • Broadcasting: Radio waves that have different frequencies are used to broadcast radio and television.
  • Communication: Several types of waves are used for communication.
  • Radio control: Radio waves can be used to send signals to control model cars, planes and boats.
  • Radio frequency identification: This identification system involves tagging on object, animal, or person with a microchip that responds to radio frequencies. it can be used to identify pets and keyless locks on doors.

Force and Motion

Zach Fluck Science blog Force and Motion Blog Sir Isaac Newton was an English astronomer, physicist, and mathematician, born on December 25, 1642. He died on March 20, 1727, most likely from mercury poisoning or old age. However, during his life, he made several contributions to modern science and advanced our understanding of physics tremendously. Arguably his most famous discovery was gravity. However, he had to use his 3 laws of motion to make this accomplishment. Newton understood that an object at rest will stay at rest, unless acted on by unbalanced forces. Therefore, if an object such as an apple is in a resting position there must be a force to make the apple fall to the ground. He discovered this invisible force to be gravity. At a young age Newton was removed from school to be a farmhand. Despite returning to school the turning point in his live was he left his hometown to attend Cambridge University. After attending Cambridge he returned to his hometown where his observat...

Chemically termolecular reactions: The fourth class of chemical reactions

Chemically termolecular reactions: The fourth class of chemical reactions Maisy Chase Up until now only three classes of chemical reactions were known. Unimolecular reactions occur when one reactant undergoes bond breaking or forming to create different products. Bimolecular reactions are where two reactants collide and then undergo bond breaking or forming. Termolecular association reactions, where two reactants collide to form a whole with a new chemical bond between the two reactants. A third molecule, known as the bath gas, then removes some of the internal kinetic energy of that molecule to stabilize it. Researchers from Columbia University , led by Assistant Professor of Mechanical Engineering Michael P. Burke, have discovered a fourth class of chemical reaction known as “chemically termolecular reactions.” This involves the breaking and bonding of three molecules. The team showed that these chemically termolecular reactions not only are major chemical pathways but also ...

Light waves, Mechanical Waves, and Radiation

  By Marc Gabay Waves are a very interesting topic, if you take the time to think about it thoroughly; for example, light waves or radiation. The kinds of light waves from our sun are visible light ways. On average, it takes roughly 8 minutes and 20 seconds for the sun's light rays to reach Earth. That being said, if the sun were to suddenly disappear out of the universe, it would take a little more than 8 minutes before we realized it was getting a bit chilly. Light travels fast, however space is so big and vast that it takes many years even for distant stars, galaxies, and/or planets to even come into sight. As a result of this, as we look onward into space, we're really looking back into time. Light waves are very interesting this way. Next, Another way that light waves are interesting is that they affect the human body in both positive and negative ways. These types of light waves can be UV light waves or infrared waves. Infrared radiation is pretty much just heat. Thi...
