x = (0.15 mm) cos (210x-120t)

what type of wave is described by this equation?

Longitudinal, transverse, angular frequency or both transverse and longitudinal

Theres really no calculation. I thinking its longitudinal because it is given as "x=". if it were transverse im thinking it would be given as "y="

At the same time im not even sure if im right
