An unpolarized beam of light is incident on a stack of ideal polarizing filters. The axis of the first filter is perpendicular to the axis of the last filter in the stack. Find the fraction by which the transmitted beam’s intensity is reduced in the three following cases.
(a) Three filters are in the stack, each with its transmission axis at 45.0° relative to the preceding filter.
(b) Four filters are in the stack, each with its transmission axis at 30.0° relative to the preceding filter.
(c) Seven filters are in the stack, each with its transmission axis at 15.0° relative to the preceding filter.
