Unpolarized light with an intensity of 655 w / m2 is incident on a polarizer with an unknown axis. the light then passes through a second polarizer with has an axis which makes an angle of 81.5° with the vertical. after the light passes through the second polarizer, its intensity has dropped to 163 w / m2. what angle does the first polarizer make with the vertical?

1.

2.

Explanation:

Polarizes axis can create two possible angles with the vertical.

first we have to find the intensity of  first polarizer

which is given as

For a smaller angle for the first polarizer:

According to Malus Law

taking square root on both sides

For a larger angle for the first polarizer:

According to Malus Law

taking square root on both sides

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

if they have a finite resultant
