The intensity of a light- beam is 10 `Wm^(-2)` and it is plane-polarised in vertical direction. It passes through a polaroid whose transmission axis is inclined at angle of `30^(@)` with the vertical. The transmitteed light- beam passes through a second polaroid whose transmission-axis is inclined at an angle of `90^(@)` with the vertical. (i) What will be the intesity of light emerging from the second polaroid? (ii) If the first polaroid is removed, then?
