Question

One way to produce a beam of polarized light with intensity I and polarization angle ? would be to pass unpolarized light with intensity I0 through a polarizer whose transmission axis is oriented such that ?TA=?. How large must I0 be if the transmitted light is to have intensity I?(see figure)

Express your answer as a decimal number times the symbol I. For example, if I0=(1/4)I, enter 0.25 * I.
