Which of the following is totally a longitudinal wave? a) Water b) Sound c) Light d) Electromagnetic e) Laser B) Sound Which part of a sound wave is related to its loudness? a) amplitude b) frequency c) wavelength d) speed e) velocity A) Amplitude Bats navigate by emitting high pitched sound waves and a) killing all the moths C) Listening for an echo within 10 meters. b) attracting various insects toward the sound. c) listening for an echo. d) calculating wave crests per second. e) hoping humans do not hear them. Which wave does not require matter to be transmitted? a) ocean wave b) sound wave c) X-ray d) seismic wave e) subsonic wave C) X-ray Which property of electromagnetic waves is measured in Hertz? a) amplitude b) speed c) frequency d) length e) energy C) Frequency The Doppler effect describes: a) how bats fly and locate their food. b) change in wave frequency when source or receiver is moving. c) change in wave frequency when neither source or receiver is moving. B) Change in wave frequency when source or receiver is moving d) how dolphins navigate in the world's oceans. e) how humans see the colors red and blue. If you are observing a light source moving very rapidly towards you, the Doppler effect predicts that the light will be: a) redshifted. b) blueshifted. c) bent. d) transmitted. e) radiated. B) Blueshifted Light passing through a window glass is an interaction called: a) transmission. b) absorption. c) scattering. d) reflection. e) the greenhouse effect. A) Transmission Compared to microwave radiation, infrared radiation: a) has shorter wavelengths. b) has longer wavelengths. c) is a faster wave. d) is a slower wave. e) is visible to the human eye. A) has shorter wavelengths The ability of microwave ovens to cook food b) are absorbed quickly by water molecules, which generates heat. depends partly upon the fact that microwaves: a) are absorbed quickly by water molecules, which does nothing to heat food. b) are absorbed quickly by water molecules, which generates heat. c) are reflected by the interior of an oven, which causes heat to be generated in the oven wall. d) tend to be absorbed in dry air and thus heat the whole oven and its contents. e) are scattered by water molecules, which helps heat the glass door of the oven. Which type of radiation can be used to sterilize medical equipment? a) microwave radiation b) ultraviolet radiation c) fluorescence d) infrared radiation e) radio waves b) ultraviolet radiation What practical use has been found for gamma rays? a) detecting the speed of a moving vehicle b) generating light and heat c) cooking food and heating water d) medical applications e) carrying radio signals d) medical applications What is the difference between general and special relativity? a) General relativity applies to accelerating frames of reference and special relativity does not. b) Special relativity is a special case for two frames of reference accelerating in opposite directions. c) General relativity can only solve problems of time dilation and length contraction; special relativity can apply to problems of large mass and the speed of light. d) Special relativity is much more complex than general relativity, requiring rigorous mathematical calculations to explain. e) Physicists have been arguing over the difference since 1915 and have not come to a consensus yet. a) General relativity applies to accelerating frames of reference and special relativity does not Which one of the following
