Q5: A spectrophotometer measures the concentration of a sample dissolved in water by shining a light through it and recording the amount of light that emerges. In other words, if we know the amount of light that is absorbed, we can calculate the concentration of the sample. For a certain substance the concentration (in moles per litre) is found by using the formula: |C=-2500 1n() Where the lo is the intensity of the incident light and I is the intensity of light that emerges. Find the concentration of the substance if the intensity I is 70% of Io. Use an appropriate standard engineering software such as MATLAB, CAS calculator, programmable calculator, Excel software, to solve and analyse this program mathematically.

A research ship in the Pacific Ocean is testing a new method of detecting pollutants in ocean water (nwater=1.3330). Their experimental apparatus includes two lasers which hang over the side of the ship and point downward into the water (the lasers themselves are suspended in the air above the surface of the ocean). One laser is violet (λ=400 nm, αH2O = 0.0044 m-1) and the other is red (λ=700 nm, αH2O = 0.6 m-1). Both lasers are very bright, with an intensity of 3600 W/m2. What is the fraction of light coming from the red laser beam that is transmitted from the air into the water? Incorrect.
