a) What is the angle of incidence that will result in maximum polarization for light reflected from the surface of liquid of index of refraction nliquid = 1.24? Express your answer in degrees and assume that the other medium is air.
b) What is Brewster's angle in this case?We use two lenses of an identical focal length of 14.0 cm to view a coin 9.0 cm from the lens. Lens one is diverging, lens two is converging.
c) What is the magnification of the image due to lens one?
d) What is the magnification of the image due to lens two?
