Unpolarized light is incident on a linearly polarizing filter oriented 30 degrees with respect to the horizontal. The light then passes through a vertically polarizing filter followed by a linearly polarizing filter oriented 60 degrees with the horizontal. If the initial unpolarized light Intensity is I, what is the final intensity that emerges from the last polarizing filter?
