1. X-rays/infared/microwaves all can be polarized a. X-ray- has highest frequency-lowest wave length 2. The light coming from a distant galaxy is found to be red-shifted-the galaxy is moving away from the earth 3. Unpolarized sunlight reflects off the surface of a lake. The reflected light is horizontally polarized. a. Unpolarized light reflects off a wall, reflected light is vertically polarized? 4. The electric field in an electromagnetic wave is increasing in magnitude at a particular time. The magnitude of the magnetic field at the same time is increasing. And vice versa: directly proportional 5. Infared/microwaves/x-rays all travel at the same speed 6. An object placed in front of a spherical mirror. The image is 1.5 times the sign of the object. The mirror is: concave a. An object placed in front of a spherical mirror. The image is .5 times the size of the

Unformatted text preview: object. The mirror is: convex. 7. An object is located 5cm in front of a mirror and forms an image 10 cm behind the mirror. The magnification is 2 a. An object is located 10 cm in front of the mirror and forms an image 5 cm in front of the mirror. The magnification is: -0.5 8. A mirror produces virtual image. This image can be seen by the naked eye a. A lens produces a virtual image. This image can be projected onto a screen but not seen by the naked eye 9. The units of the index refraction are: no units 10. When the light travels from one medium to another, what happens to the angle of refraction if the angle of incidence Is doubled. The angle of reflection: cant not be determined due to snells law??...
