Physics of Light in the North Coasts of Persian Gulf (Bushehr province) during Winter Season

We present a study to field measurement and laboratory experiments of light for university students in physical oceanography. During 6thto 8thof February 2009 in two stations of Bushehr province central coasts, sampling of sea water and other effective physical parameters were carried out. The effects of laser light in 532, 659, and 980nm on the collected water samples in two different stations were studied. Then light attenuation coefficient and the amount of light penetration percentage for these stations at different depths were calculated. According to the results of this study, light attenuation coefficient in the first station, the wave length for red and infrared lights is more than the wave length for green light. For red and infrared wave lengths the amount of light absorption in the first station is more than the second one. The salinity, temperature, and cloud cover parameters are not effective in the amount of light absorption. The effective factor in increasing the amount of light absorption in this station than the second station is water turbidity
