Yes, it's a.firezap said:It's a. I look at the graph at x = 3cm and displacement = -1cm. The dot would move left 1cm, so the dot is at 2.
Longitudinal waves are a type of mechanical wave that travel through a medium by creating compressions and rarefactions. These waves are characterized by the particles of the medium moving parallel to the direction of the wave.
In a snapshot graph of a longitudinal wave, the wave will appear as a series of compressions and rarefactions. The distance between each compression or rarefaction represents the wavelength of the wave, and the amplitude of the wave is the distance between the crest (highest point) and trough (lowest point) of the wave.
To ensure that you have chosen the correct snapshot graph for a longitudinal wave, check that the wave is moving in the correct direction (parallel to the x-axis) and that the compressions and rarefactions are evenly spaced and have the correct amplitude and wavelength.
A longitudinal wave travels through a medium by creating compressions and rarefactions, while a transverse wave travels through a medium by creating crests and troughs. The particles in a longitudinal wave move parallel to the direction of the wave, while the particles in a transverse wave move perpendicular to the direction of the wave.
Longitudinal waves have many practical applications in everyday life. Some examples include sound waves (which are longitudinal) used for communication and medical ultrasound imaging, seismic waves used to study and predict earthquakes, and shock waves used in supersonic travel and medical treatments.
