Wonderful World of Waves

Journal 15: Over this crazy weekend, there was so much physics around me ranging from the mechanics of the rides during the fair, to the application of Newton's third law with the bounce houses, and even the correct use of physics with kinematics to the baseball and football game.  However, I will be focusing on my experience with the concept of waves.  During this awesome break, during the fair, when it was my 5 hour shift as a food runner, one of the calls called for two tubs of kalbi.  These tubs contained the meat and the marinade sauce and were extremely heavy.  Upon driving the carts, I had to go back and adjust the boxes, then I saw the juice sloshing back and forth and the rising of the kalbi created a wave opposite to that of the moving juice.  While the marinade as far as I could tell probably was not moving at its natural frequency the two waves made by the kalbi and the cart created super crests in the tub.  The sloshing of the sauce showed the waves to be transverse waves and not of the same frequency or amplitude since the waves were of different amplitude.  Then the waves would pass through one another hit the sides of the tub and then go back until they settled.  However, the jerkish movements of the carts, the constant stop-and-go, and the bumps would reinitiate the same cycle as the juice would naturally slosh and then the kalbi would rise and make opposing waves. Hope you guys enjoyed the fair I had a lot of food: 3 Waiola Shave Ices, 3 Smoothies, 1 Huli Beef Sandwhich, 1 Pizza, I Korean Mixed Plate, 6 Malasadas, 2 Teri-Cheese Burgers, and lots of Water.  Yeah fatty, but then I ran a lot and walked a lot and now I should work out.  Bye!  

Stop the Music

Journal 14: Today, after listening to music for awhile my ears began to ring incessantly.  I had learned that sound resonates and that the blast of my headphones had reverberated in my ears.  In addition I learned that, shown with tuning forks, by placing the fork against another object the sound became amplified.  The sound originally resonating from fork when in contact to the table bounces off and the sound waves travel further and are louder because its molecules are in contact and bump into others such as those of the table the tuning fork was placed against.  Likewise, i recently learned the build-up of earwax can also create such a ringing sound because as the sound waves travel rather than just simply bouncing and coming in touch with the ear drum, like the table, the earwax serves as another medium and object in which the sound waves interact and bounce off as well.  Thus the earwax can amplify the sound being heard and the ring you hear is the sound resonating as the sound molecules vibrate and hit against each other and the wax.  This is one explanation of ear ringing, others include the falling out of an sound receptor follicle, since overtime the vibration of the sound over time loosens up the follicles and a ringing sound occurs as one falls out.  The vibration of the follicle causes the ringing as it falls out and those sound waves resonate as the molecules move back in forth in compressions and rarefactions.  Also the continuous playing of music can damage the follicles and lead to a loss of hearing, aging also generally leads to a loss of hearing as a normal human's hearing range continues to drop from the high 20,000 Hz to lower levels.
