In many transparent materials, dispersion causes different colors (wavelengths) of light to travel at different speeds. This can cause problems in fiber-optic communications systems where pulses of light must travel very long distancmade of silicate crown glass, calculate the difference in travel times that two short pulses of light take to travel 15 km in the fiber if the first pulse has a wavelength of 700 nm and the second pulse has a wavelength of 500 nm.

A horizontal 5.0 mW laser beam that is vertically polarized is incident on a polarizing sheet that is oriented with its transmission axis vertical. Behind the first sheet is a second sheet that is oriented so that its transmission axis makes an angle of 30° with respect to vertical. What is the power of the beam transmitted through the second sheet? What would the power of the beam transmitted through the second sheet be if the lazer beam was Unpolarized?
Polarised light is incident on crossed polarisers (i.e. polarisers with perpendicular polarisation axes). The first polariser the light encounters is aligned with the light polarisation. A third polariser is inserted between the crossed polarisers, with its polarisation axis rotated by 0.28 radians relative to the first polariser. What is the percentage of light intensity transmitted through all three polarisers?

You have three polarizers. If incident light is polarized at 30 degrees to the vertical, aligned with the transmission axis of polarizer B (which also has its transmission axis 30 degrees to the vertical), and polarizer C has transmission axis at 90 degrees to the vertical, in what order should the polarizers be placed for maximum intensity? Is there more than one answer? Would it be A,B,C or B,A,C?
