What is the speed of sound through both the aqueous fluid and vitreous gel in meters per second?

1450 meters per second
1500 meters per second
1532 meters per second
1580 meters per second

The correct answer is: 1532 meters per second

The speed of sound in different media is influenced by the density and elasticity of that medium. In the context of ocular anatomy, the speed of sound through aqueous humor, which is the fluid found in the anterior segment of the eye, is typically around 1450 meters per second. The vitreous gel, found in the posterior segment, has a slightly higher speed of sound, approximately 1532 meters per second. Choosing the value of 1532 meters per second reflects an understanding of the properties of the vitreous gel, which has a denser molecular structure compared to aqueous humor, allowing sound to travel faster through it. Therefore, considering both the aqueous and vitreous media, the combined average speed of sound you would expect in the eye aligns closely with this value. Understanding the specific speed of sound in these ocular fluids is crucial for applications in ophthalmic diagnostics and imaging techniques, such as ultrasound biomicroscopy and echography, as it helps in accurately interpreting results.
