Types of the Waves  
By: Alzahraa Alrubaiey 
                     Waves can be help full but sometimes they might some serious impact on the human body. Without waves we would not have the life we have today. The types of waves include long radio waves, radio waves, microwaves, visible light, infrared, ultraviolet, x-rays, and gamma rays. Each of them helps us in many different ways. Radio waves are used every day in our lives, as they are used to broadcast everything that you hear on the radio and see on your television.  Microwaves are the most important waves in today’s world because they are used in everything that includes technology. Infrared rays are used to detect an object that has heat, and to tell the temperature of that object. Visible light is what all of us see every day, it consists of all the colors that us humans can see, and is used to, well, light things up. Ultraviolet It is emitted from the sun in very large quantities and used in tanning booths. It is very harmful to skin after a period and is confirmed to cause skin cancer. Gamma rays are emitted by quasars, dying stars, and nuclear bombs. This ray has a lot of penetrating power and is conventionally used in nuclear weapons. X-rays are most recognized in their medical usages and have revolutionized the identification of problems with the skeletal structure. X-Rays are also used in security systems around the globe and have caught a lot of people with illegal weaponry on them.  
              Some of these waves can be very harmful, some of these waves can cause burns and cancer. The effects usually occur at lower frequencies, because at low frequencies, external electric and magnetic fields induce small circulating currents within the body.  The main effect of radiofrequency electromagnetic fields is heating of body tissues. There is no doubt that short-term exposure to very high levels of electromagnetic fields can be harmful to health. 
                The effects of these waves are very harmful. Radio waves interference from other radio waves can be a problem, range can also be a problem. High exposures of microwaves can cause cancer and burns. Infrared rays can cause minor burns if exposed to skin for long periods of time. A bright light of visible light (such as the sun) can blind you. Ultraviolet rays causes skin cancer, damages eyes, in large amounts, damages immune system. Even small amounts of x-rays can cause many forms of cancer and requires large equipment to use effectively. Gamma rays lingering radioactivity from bombs can prove detrimental to human health. 
                These waves can be very helpful in the future. Now a days we use these waves as part of our everyday lives. We can find them all over the world because they include technology, medical usage, and everything that we use. In the future these waves are going to help us to be more modern, mostly in technology equipment.

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...
