T or F: Vollage is a measure of the potential energy of a charge in an electrie field. 2. The function of a capacitor is to S. If the plates of a capacitor are pulled apart without losing any charge, the voltage on the plates will 4 TorF The charges on capacitors conmocted in series are equal 5. The resistance of a semiconductor (a) increases or (b) decreases with an increase in temperature. 6 Resistivity is an (a).intrinsis or (b) extrinsis property of materials 7. A voltmeter measures (a) yolagsV: (b) diffcrenses in voltags AW or (e) clsstron olts.cV Tor F The radius of curvature and focal length of a thin lens are approximately identical values. 9. For concave mirrors and convex lenses, incident parallel rays converge at the 10. Which of the following cannot form a real image when used by itself without other opties? a. concave mirror or a convex lens c convex mirror or a convex lens b. convex mirror or a concave lens d. concave mirror or a concave lens 11. The wavelengths of visible light range from 12. In above, the longest wavelength corresponds to the colorand the shortest to 13. Give the order of the following in terms of increasing freguensy (1 lowest frequency). nm to om _ gamma rays, __ TV-?visible light,-x-rays,-?infrared,-microwave 14. If the refractive index of water is 1.333, the speed of light in water is 15. Total internal reflection occurs only when a light ray travels from a medium of (a) high or (b) low refractive index into a m/s. medium of (c) highcr or (d) lower refractive index. 16. A typical application for total internal reflection is 17. T or F The speed and frequency of light is the same in any material 18. The law of reflection states that 19. The variation of refractive index of a material with wavelength is called 20. Your enlarged image in a makeup mirror is (a) rcal or (b) virtual and is (c) crect or (d) inyertedExplanation / Answer
16) Optical fiber communication
17) False. Frequency is same but sped is different in different materials.
18) The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane. Furthermore, the angle of reflection is equal to the angle of incidence.
19) Dispersion
20) (b) virtual
and
(c) erect
