Answer:
A) 58 degree
Explanation:
When unpolarized light passing through first polarizer then the intensity of light becomes half as it will get polarized
So let say the intensity of unpolarized light is "Io" then after passing through first polarizer the intensity will become half
Now when this polarized light passing through another polarizer then the intensity of light is given by Malus law
As per Malus law if the angle between two polarizer axis is inclined at some angle
then it is given as
False it refers to frequency
This is because of the conservation of angular momentum, which allows most planets to spin in the same direction, but Venus and Uranus have seem to ignore this as they spin in different directions, as Venus spins clockwise and Uranus is on its side
