Aray of light leaves an object and passes through the focal point on the same side of a converging lens. the ray is then incident on the lens.

which one of the following statements correctly describes the subsequent path of the light after it leaves the lens?
a) the ray passes through the focal point on the opposite side of the lens. b) the ray travels parallel to the central axis. c) the ray travels along the central axis. d) the ray passes through the lens undeflected as if the lens were not present. e) the ray is reflected back on itself through the same focal point.

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?
