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
The Attempt at a Solution
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
