Which of the following is not a medium for sound waves?

Which of the following properties is NOT a factor to determine the speed of sound?Aelasticity BtemperatureCfrequencyDdensity

Which of the following correctly describes sound waves?A They are transverse waves.B They are a part of the electromagnetic spectrum.C They are longitudinal waves.D They do not require a medium for transmission.

Which of the following statements about sound waves is incorrect?Sound waves cannot travel through a vacuumSound waves are longitudinal wavesIt is not possible to measure the wavelength of a sound waveThe vibrating particles which make up a sound wave form more dense regions called compressions and less dense regions called rarefactions2Domestic cats can hear sound waves with a maximum wavelength of 6 m.  What is the frequency of a sound wave with this wavelength?  The speed of sound in air is approximately 330 m/s.55 Hz324 Hz0.018 Hz (2 s.f.)1,980 Hz3What is the function of the cochlea?It allows the ear to detect very quiet soundsIt protects the ear against infectionIt controls air pressure within the earIt converts vibrations within the ear into electrical signals4What is the range of frequencies over which the human ear can detect sound waves?From 20 Hz to 2,000 HzFrom 20 Hz to 20,000 HzFrom 20 Hz to 20,000 kHzFrom 20 Hz to 200,000 Hz
