A beam of polarized light strikes two polarizing sheets. The characteristic directions of the second is 900 with respect to the incident light. The characteristic direction of the first is at angle ø with respect to the initial beam. Find angle ø for a transmitted beam intensity that is 0.10 times the incident beam intensity.
