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.
Eyeball. The main part of the eye is the eyeball (also known as the globe), which is mostly filled with a jelly-like material called vitreous humor.
