= = = Making Waves = =Description:= In the above photo, a high-speed camera has captured water droplets falling into a pool of water. The impact has caused waves to occur and the stagnant water to rise up in a splash. Additionally, one can see the reflected image of the background in the water droplets, reading "H20". States of Matter Water, as unique form of matter, is seen uniquely reacting in this photo. First, the property of hydrogen bonding is what creates water droplets in the first place. When one attempts to separate water, the molecules drag together and fight to sustain their form, this is called cohesion. This drag also occurs when the droplets hit the pool. This is the action of displacement, and as the new droplets enter the pool at what appears to be high speed, the water currently in the pool is forced out of the way. Connecting back to hydrogen bonding, the splash creates one large form. Waves The ripple effect seen in this photo is an example of waves. Waves actually show the movement of kinetic energy, not water. The kinetic energy of course, comes from the impact of the droplet hitting the water--the same way water ripples through a pool when someone cannonballs. This is the water's way of absorbing the force. Think cars and momentum: During the egg crash lab earlier this year, our bumpers smashed in order to absorb impact. However, a pool of water cannot smash the same way, and instead disperses the remaining kinetic energy in centric ripples. Light The photo displays the concept of light because of the reflected images found in the water droplets. Though this may look photoshopped, it is actually real. This effect is created the same way your eyes and a camera lens works. The spherical shape the water assumes acts as a kind of lens, it reflects light and therefore displays an image. Notice that the image is flipped, similarly to how the eye receives reflected light and flips the image received.
