Light from a laser is plane polarized in the vertical direction

Light from a laser is plane polarized in the vertical direction. If a linear polarizer is placed in the beam at an angle of 45 degree from the vertical axis, what percentage of the light will pass?

Solutions

Expert Solution

let the incident intensity is Io

Output intensity = Io * cos(theta)^2

Output intensity = Io * cos(45)^2

Output intensity = 0.5 *Io

percentage of intensity passing is 50 %
