Three different red lasers were used to test and calculate transmission through different materials. the transmission was measured with an energy detector and calculated with an in beam and out beam measurement. All the datta was then averaged for each item and then compared in a graph.
Items such as water, canola oil and steam had very high transmission whereas ice, carbon dioxide gas and olive oil had much lower transmission.
Darker liquids like olive oil, transmitted less than the lighter liquids such as water and canola oil. Clear plastic and glass allowed more energy to pass through than the darker plastics. This proves my hypothesis that clearer objects would have a higher transmission than darker objects.
This project evaluated whether red lasers transmit better through clear objects or darker ones?
