Question

factors that impact the speed of sound as it travels through water temperature salinity longitude light latitude hydrophones previous

Explanation:

The speed of sound in water is affected by temperature (higher temperature generally increases sound speed) and salinity (higher salinity can increase sound speed). Longitude, latitude, light, and hydrophones do not directly impact the speed of sound in water. Longitude and latitude relate to location on Earth, light is a different form of energy (electromagnetic) not directly affecting sound speed in water in the context of the question, and hydrophones are devices to detect sound, not factors that change the speed of sound itself.

Answer:

Temperature: impacts the speed of sound in water.
Salinity: impacts the speed of sound in water.
Longitude: does not impact the speed of sound in water.
Light: does not impact the speed of sound in water.
Latitude: does not impact the speed of sound in water.
Hydrophones: does not impact the speed of sound in water.
