8) Which of the following is false (2pts) sound can travel in a vacuum light can travel in a vacuum light and sound can travel through liquids light and sound can travel in air 9) Interference occurs (2pts) with all types of waves only with sound waves only with transverse waves only with longitudinal waves 10) The speed of sound (in solid. liquid, and gases) (2pts) is greatest in a liquid and least in a solid is greatest in a solid, and lowest in a gas is lowest in a liquid and highest in a gas. Dis greatest in gas, and least in a solid. 11) Sound travels slowest in (2pts) O iron fresh water O sea water O air 12) The range of frequencies humans can hear most clearly (2pts) 20Hz-20,000Hz more than 20.000Hz. 3000Hz-5000Hz less than 20 hertz (3) Tight (2pts) travels faster in air than sound. Wintravels faster in solids than in vacuum. cannot travel in a vacuum is a mechanical wave. 14) The louder a sound the greater the (2pis) wavelength frequency pitch amplitude 15) Consider two sound waves one of 40 Hertz and the other of 50 Hertz, Which of the following is (2pis) correct about them 40 Hertz is lower in frequency and higher in wavelength than 50 Hertz. 40 Hertz is higher in frequency and lower in wavelength than 50 Hertz 40 Hertz is lower in frequency and lower in wavelength than 50 Hertz. 40 Hertz is higher in frequency and higher in wavelength than 50 Hertz Previous 1 1213141515 Next
