pressure waves
Which of the following is an example of a longitudinal mechanical wave

What is one of the main differences between mechanical and electromagnetic waves?
Electromagnetic waves are always transverse, mechanical waves are always longitudinal.
Electromagnetic waves do not need a medium to travel in but mechanical waves do.
Electromagnetic waves do not transfer energy, but mechanical waves do.
Electromagnetic do not have wavelengths but mechanical waves do.
What is the difference between longitudinal and transverse waves?
Longitudinal waves move the medium parallel to their direction of propagation, transverse move the medium perpendicular to their direction of propagation.
Longitudinal waves move the medium perpendicular to their direction of propagation, transverse move the medium parallel to their direction of propagation.
Longitudinal waves are standing waves and do not propagate, transverse waves propagate outwards from their source.
Longitudinal waves propagate outwards from their source, transverse waves are standing waves and do not propagate.
What is the relationship between frequency and wavelength?
Directly Proportional
Quadratic
Inversely Proportional
Logarithmic
