The Importance of Mechanical Waves and Electromagnetic Waves

In our world, there are many different kind of waves. Transverse waves which moves up and down unlike longitudinal waves which stream and move sideways. These two kinds of waves are 2 of 3 waves that can be describes as mechanical waves. The third kind that goes under the category of the mechanical waves are surface waves. The only prospect that is required in order to transmit these kinds of beacons is matter. Without matter, the waved wouldn't be able to be transmitted. One of the most important kind of mechanical waves that we use and hear in our everyday life is sound. we hear each other because the particles of sound are moving through the air and are reaching us. Another use that is known to us that is based on mechanical waves is ultrasound. According to Wikipedia.com ultra sound is "cyclic sound pressure with a frequency greater then the upper limit of human hearing." Ultrasound is used for the Realm of medicine, especially in sonography to see the baby in the mothers womb.

Another conspicuous kind of wave that is important to our everyday life is the electromagnetic wave. These frequencies are used in microwaves, X-rays, TV, Radio, and the most important of all light! According to http://www.colorado.edu electromagnetic waves are "wavy disturbance that repeats itself over a distance called the wavelength." Without electromagnetic waves, we would not be able to live, due to the fact there would be no light (and according to a fact Marko Jovsic gave last class, humans will be able to survive only 8 minutes without the sun which produces our light), we would not be able to listen to music in the radio while our parents are driving us to a far place, we would not be able to watch movies on the TV, and we would not be able to pop popcorn!
