There are many ways to determine the speed of sound. The method we will use in this lab is both fairly. straight forward and the equipment needed is fairly minimal. We will be creating sounds and recording. them with two microphones. We will measure the di erence in distance between the paths the sounds take.
High pressure inside of the eye is caused by an imbalance in the production and drainage of the fluid in the front of the eye (aqueous humor). The channels that normally drain the fluid from inside the eye consequently do not function properly or are blocked.
Usually holes and tears do not mean you will have serious vision problems right away. However, retinal holes and tears may cause fluid from the center of your eyeball to leak behind the retina. If enough fluid gets behind the retina, the retina can separate from the back of your eye. The detached part of the retina will not work properly.
