Which of the which of the following statements is accurate?

a. compressions and rarefactions occur throughout a transverse wave.
b. amplitude of longitudinal waves is measured at right angles to the direction of the travel of the wave and represents the maximum distance the molecule has moved from its normal position.
c. the wavelength of both traverse and longitudinal waves is measured parallel to the direction of the travel of the wave.
d. sound waves passing through the air will do so as transverse waves, which vibrate vertically and still retain their horizontal positions.

following statements is accurate?

Correct answer is option C( The wavelength of both traverse and longitudinal waves is measured parallel to the direction of the travel of the wave.

Explanation:

Longitudinal waves:

Longitudinal; waves are the waves in which disturbance occur in direction parallel to the direction of propagation of wave. in this types of waves compression and rarefaction created due to vibration off particle. Wavelength of longitudinal waves is equal to the distance between two successive rare fractions or compression. It means  wavelength of longitudinal wave is measured parallel to the direction of the travel of the wave.

Transverse waves:

Transverse waves are the waves in which vibration of particles occur in the direction perpendicular to the direction of propagation of wave.Wavelength of transverse wave is equal to the distance between two successive crust and trough. This distance is parallel to the direction of propagation of wave.

Therefore the wavelength of both traverse and longitudinal waves is measured parallel to the direction of the travel of the wave.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
