Method:
We used a Cool Pix 990 to take photographs of the milk splashes. We used a milk drop contraption to do this(View Setup). We mounted the camera about 8 inches away from where the splashes would land. We used a vibrating disc as a landing surface and to make our images different than others. We kept the resistance the same but varied the frequency of the vibrating disc to get different effects and ripples. The flash was connected to the photo gate, and every time the drip would fall it would set off the flash. By varying the sensitivity of the photogate, we could obtain photographs of the splash in different stages.
Setup:
Milk dropper: The milk dropper was placed above the vibrating disc.
Vibrator: The vibrator served as a platform for the drops to splash on. The vibrating of the disc gave different effects and ripples.
Camera: The camera was placed about 8 inches away from the disc.
Photogate: When the milk dropped through the photogate it broke infrared beam which caused a flash.
Time control box: The time control box was used to change the sensitivity of the photogate. By varying the sensitivity, the flash showed different stages of the splash.
Oscillator: We varied the frequency with the oscillator.
Flash Unit: The flash unit was connected to the photogate and the time control box. The flash provided the light for us to take our photographs.
