The refractive index of the ocean water:
- A.
Increases with salinity
- B.
Increases with temperature
- C.
Decreases with salinity
- D.
Decreases with temperature
Correct Answer
A. Increases with salinityExplanation
The refractive index of a medium is a measure of how much the speed of light is reduced when it passes through that medium. Salinity refers to the concentration of salt in water. As the salinity of ocean water increases, the refractive index also increases. This is because the presence of salt particles in the water increases the density of the medium, causing light to slow down more when passing through it. Therefore, the refractive index of ocean water increases with salinity.Rate this question:
