Which of the following does not describe a method of achieving polarization?
1.Light hits a reflective surface at a particular angle, dependent on wavelength and index of refraction. The light which reflects is polarized in one direction, and the light which is transmitted is polarized perpendicular to the reflected light. 2.Unpolarized light encounters material made of parallel long-chain molecules. The portion of the light in line with the chains is transmitted; the rest is absorbed. 3.Light collides with air or other gas molecules, which absorb the energy. Electrons inside the molecule begin to vibrate, emitting polarized light much like a radio antennae. 4.Light is sent through an optically active material.
Thin Lenses: Is it possible to see a virtual image?
A. No, since the rays that seem to emanate from a virtual image do not in fact emanate from the image. B. No, since virtual images do not really exist. C. Yes because the rays that appear to come from a virtual image can be focused by the eye just like those from an object. D. Yes, but only by using an additional lens to form a real image before the light reaches the eye.
