The laptop screen is viewed through a polarising filter.
Initially the brightness of the screen appears normal.
The filter is rotated gradually through an angle of 180°.
How does the brightness of the laptop screen appear after the filter has been rotated by 90°, and
then by 180°?
After a rotation of 90 After a rotation of 180
