Don't use ch***gg, answers are unclear and kind of wrong. Thank you!

7. Un-polarized light with intensity in passes through two polarizing films separated by a distance- a. At what point will the polarizing films be oriented so that they are in the same direction? (2 marks) b. If the polarizing films are initially oriented in the same direction, and then the second polarizing. film is rotated clockwise by an angle of 30, determine the intensity of light between the polarizers and after it has passed through both polarizers. (2 marks) c. If the first polarizing filter is now rotated counter clockwise through an angle of 60, determine the intensity of light between the polarizers and after both polarizers. (2 marks]
