1- wave velocity is related toa- period b-wavelength c-amplitude d-all of these2- wave amplitude is related toa- wave velocity b- frequency c- energy d-wave length3-which of the following radiation has the smallest frequency?a- infrared b- visible c- ultraviolet d-x-rays4-light can travel to the earth from a distant star but soundcannot.why is it?a- light is an electromagnetic wave and sound requires amediumb- the sun does not make soundc- light is a longitudinal wave and sound is a transversewaved-the statement is false both will travel in empty space5- resonance occurs whena- two different objects vibrate with different frequenciesb- two different objects produce beatsc- an object having certain natural frequency is set invibration by second object vibrating at that frequency.d- an object produces a sound.6- when oscillator is driven in resonance,a- there are no standing wavesb-all natural frequencies are presentc- there is maximum energy transferd- any driving frequency may be used.7-imags of objects are formed by lenses because ofa- refraction b-diffraction c-internal reflectn d-all ofthese8- complete destructive interference occurs for two waves ofthe same amplitude and frequency when the waves are out of phaseby:a- zero degreeb- 90 degreesc- 180 degreesd-360 degrees9-what is the wavelength in meters of radio waves produced bya radio station with a frequency of 1400 KHz?a- 2.1 X 10^7 mb-2.1 X 10 ^12mc- 4.23 X 10 ^14d- 2.1 X 10^2m10- what is the frequency in hertz of a sound wave( v=340 m/s)with wavelength of 0.20m?a- 1.7 X 10^3 Hzb- 17 X 10^3 Hzc- 1.7 X 10^2d- 68Hz11- a series of ocean waves each 6.0m from crest tocrest moving past an observer at a rate of 2.0 waves per second haswhat speed?a-3 m/s b- 12 m/s c- 33 m/s d- 720m/s12- how many times greater is the speed of red light(700nm)than the speed of violet light(400nm) in a vacuum?a- 1,100 nm b- 300 nm c- 175times d- both have the same speed13- how many times faster is the speed of light invacuum than the speed of sound in air?a- 10^6 timesb- 10^ -6 timesc- 300 X 10^6 timesd- 300 times14- the speed of light in diamond is 1.24 X 10^8 m/s. whatis the index of refraction of diamond?a- 2.42 b-242 c- 0.41 d- 1.2415- a particular material has an index of refraction of1.25. what percent of the speed of light in vacuum is the speed oflight in the material?a- 125 %b- 8%c- 12.5 %d- 80 %16- an object is placed 8cm from a converging spherical lens.The general characteristics of the image for a lens witha focal length of f=12 cm.a- real, inverted, and enlargedb- virtual, upright, and enlargedc- virtual, inverted and smallerd- real , upright and smaller17- a simple magnifying glass has a focal length of 6.0cm.an object is placed 4.0 cm from it. Give the characteristics of theimage.a- virtual, inverted andsmallerb- real, inverted and enlargedc- virtual, upright and enlargedd- real, upright and smaller
