A beam of light is passed through a first linear polarizing filter. A second polarizing filter is placed after the first one. When its polarizing axis is rotated by θ=34 degrees with respect to the first filter, the light intensity decreases as compared to when θ=0. What is the ratio of the light intensity after rotating the second polarizer to the intensity when θ= 0? Give your answer in decimal form. If angle θ is adjusted until I/I₀ = 0.28, what is angle θ?
