The intensity of light transmitted through an absorbing solution is given by the Beer-Lambert law, 1 = lo exp (-€*cxd), where lo is the intensity of the light source, ε is the molar absorptivity of the absorber, c is the concentration of the absorber in the solution and d is the distance travelled by the light through the solution. Calculate the molar absorptivity of Rhodamine 6G dye given that only 20% of the light source's intensity is transmitted through 1...

A beam of partially polarized light (a mixture of vertically polarized and unpolarized light) of intensity 500 Wimm' is incident on a polarizing sheet. In order to determine the relative intensities of the polarized and unpolarized portions of the beam, the light is sent through a vertical polarizer, and the intensity is noted to drop to 300 Wm Mathematical Analysis a. Determine the intensities of the polarized and unpolarized portions of the beam b. What is the transmitted intensity if...
