How does light and intemperate travel in pee - Essay ExampleUsually, temperature varies from about 28F around either North and South poles, or 90F or above near the Equator or around the Tropics.Salinity or grossness of the sea piss, differs roughly from 32 to 38 ppt. Its impact on sound waves or sound make haste is often minor, but salinity rates by the virtue of its locationfor instance, near the land or masses of sea icecan have remarkable impact.In constant coefficients, change in swiftness of sound through temperature changes increases by +3 meters per plunk for while at that place is approximately +.5 meters per southward per change in 30 meters in sea depth and by change of per ppt. salinity, about +1.2 meters per second The SSP, or sound speed profile, is used to measure the combined effects of temperature, salinity and depth in relation to sound speeds. It is a vertical column of water consisting of an iso-speed layer (also called the mixed surface layer). on a low er floor it, there is a seasonal thermocline which measures down to 250 meters and below, the larger main thermocline. Due to the changes of the waters temperature, there exist variations in the SSP. Under the main thermocline, the temperature is usually constant. Also, because of depth, changes in pressure slowly increase and then give the dominant impact on the SSP.Absorption occurs when the energy in the sound waves is absorbed by the water itself, as sound moves through a body of water. It is followed by the shrinking of the original sound waves magnitude (amplitude).Light also travels in water, as sounds do, since it goes in waves. Water absorbs light and its different wavelengths at different values depending on the depth of the body of water, or the clarity or turbidity of the water. The speed of light depends on the optical density of the waterand light travels more slowly in water than it does in air.As water absorbs light, it reduces the lights quantity and
