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.
Dry eye disease is an irritating and occasionally painful condition involving a reduction of (or imbalance between) one or more of the tear film layers. Mucous forms the innermost layer of the tear film. It is made by special cells in the conjunctiva (the thin, delicate membrane that covers the white part of your eye). Mucous helps the overlying water layer adhere to the eye. Water composes the middle and largest of the three tear layers.
