Define resolving power of a grating. Derive the expression for the resolving power of
the mth principal maxima.
The axes of a polarizer and analyzer are at right angles to each other. A third polaroid
sheet is placed between them with the axis at 45° to the axes of the polarizer and
analyzer. (a) If unpolarized light of intensity I, is incident on this system, what is the
intensity of the transmitted light? What is the intensity of the transmitted light when
the middle polaroid is removed?
