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.
Aqueous humor is the: - jellylike substance behind the lens and in the posterior cavity. - watery liquid found in the anterior cavity of the eye. - mucous membrane lining the eyelids. - pigmented muscular structure. - watery liquid found in the anterior cavity of the eye. The lacrimal glands are the: - mucous membrane linings of the eyelids covering the anterior portion of the sclera. - anatomic structures that produce tears. - jellylike substances found behind the lens in the posterior cavity of the eye.
