Question

The intensity of a polarized electromagnetic wave is 14 W/m2 .

part a) What will be the intensity after passing through a polarizing filter whose axis makes the angle = 0with the plane of polarization?

part b) What will be the intensity after passing through a polarizing filter whose axis makes the angle = 30with the plane of polarization?

part c)What will be the intensity after passing through a polarizing filter whose axis makes the angle = 45with the plane of polarization?

part d) What will be the intensity after passing through a polarizing filter whose axis makes the angle = 60with the plane of polarization?

part e) What will be the intensity after passing through a polarizing filter whose axis makes the angle = 90with the plane of polarization?

I= I0 x Cos2()

1) I = 14 W/m2

2) I = 10.5 W/m2
3) I = 7 W/m2
4) I=3.5 W/m2
5) I= 0
