Question

Which of the following statements is NOT true? 1)Fiber optic cables make use of total internal reflection to transport light down the cable 2)If the electric field in an EM wave oscillates along a line perpendicular to the direction of travel, the wave is said to be linearly polarized 3)The dependence of the index of refraction on wavelength is called dispersion 4)If linearly polarized light encounters a polarizing sheet, the intensity of transmitted light is proportional to the sine of the angle between the polarizing sheet and the light

Explanation / Answer

4)If linearly polarized light encounters a polarizing sheet, the intensity of transmitted light is proportional to the sine of the angle between the polarizing sheet and the light.

It depends on the square of the cosine.
