Light that is polarized along the vertical direction is incident on a sheet of polarizing material. only 92% of the intensity of the light passes through the sheet and strikes a second sheet of polarizing material. no light passes through the second sheet. what angle does the transmission axis of the second sheet make with the vertical?

73.5°

Explanation:

I = I₀ Cos²Ф.

.92 = Cos²Ф

Ф = 16.5°

So first sheet makes an angle of 16.5° with the vertical.

Second sheet must be perpendicular to the first one because it blocks the whole light. So second sheet makes an angle of 90 + 16.5 = 106.5° with the vertical.That is 73.5 ° with the vertical. Or it may form an angle of 90-16.5 =

73.5° with the vertical when we consider in counter-clockwise direction.

i think they are all correct

explanation:

they seem good

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
