Welcome to your Light Waves(Senior Class Physics Study by Topics) NAME EMAIL PHONE NUMBER 1. After randomly polarized light passes through a polarizer, it istotally blocked.randomly polarized.partially polarizedtotally polarized.2. What is the wavelength of light waves if their frequency is 5.0X1014 Hz?6.0 mm0.6 micro m0.06 mm0.60 m3. Lenses are used in spectacles to treat some vision defects. The two main lens types are converging lenses and diverging lenses. Diverging lenses always produce virtual, diminished images.Which row of the table describes the images produced by a converging lens? Type of imageSize of image AOnly realOnly magnified BEither real or virtualEither magnified or diminished CEither real or virtualOnly magnified DOnly virtualOnly diminishedCABD4. Light is best described as a:Particle and WavePointWaveParticle5. If the distance from a light source to a screen is doubled, the illumination on the screen will benthe sameone quarter as muchtwice as muchhalf as much6. This types of mirror has a surface that curves inward:Opaque MirrorLongitudinal MirrorConcave MirrorConvex Mirror7. In your eyes, these detect light brightness:RodsLensesIrisesCones8. In this example of constructive interference, what increases?FrequencySpeedWavelengthAmplitude9. Which section of the electromagnetic spectrum is emitted as thermal radiation?Ultra-violetVisible lightGamma rayInfra-red10. The wavelength of ultraviolet radiation is 400nm. If the speed of light in air is 3x108m/s the the freqency of the ultraviolet radiation is1.2 e11 Hz7.5 e14Hz1.3 e-15 Hz7.5 e5 Hz11. The direction of the path taken by light is calledlocuslinebeamray12. Shadows and eclipses result from thediffraction of lightrectilinear propagation of lightreflection of lightrefraction of light13. The distance from the dotted line to Point A, or the distance from the dotted line to Point D is known as the ______________.PeriodFrequencyWavelengthAmplitude14. All electromagnetic waves travel through a vacuum atthe same speed.speeds that are inversely proportional to their frequency.speeds that are proportional to their frequency.None of the above.15. How long does it take light to travel 1.0 m?3.3 micro-s3.3 ms3.3 ns3.3 s16. What is the wavelength of a 92.9 MHz radio wave?32 m32 cm3.2 m32 mm17. An image in which no light rays pass through it is called aReal ImageVirtual ImageReflectionRefraction18. When waves in phase combine, it is called:Destructive InterferenceConstructive CombinationConstructive InterferenceDestructive Combination19. Which does not normally use infra-red radiation?intruder alarmtelevision remote controllerelectric grillsunbed20. The main difference between a radio wave and a light wave is itswavelength.none of the abovebothspeed.21. The wave speed equation is v = frequency x wavelength.If the velocity of the wave is 400 m/s and the wavelength is 2m, what is its frequency?400 Hz20 Hz200 Hz800 Hz22. Which of these colours appears in a pure spectrum of visible light?BrownBlackYellowWhite23. An image in which no light rays pass through it is called aVirtual ImageRefractionReal ImageReflection24. Which of the following are properties of a plane mirror image?A. The image is the same size as the object.B. The image is upright.C. The image is laterally inverted.B and CA, B and CA and BA only25.
