Question

A transverse wave travels along the $z-$ axis. The particles of the medium must oscillate

• A. along the $z-$ axis
• B. in the $x-z$ plane
• C. in the $y-z$ plane
• D. in the $x-y$ plane

Answer 1

The correct option is D in the $x-y$ plane

We know that in a transverse wave, vibration of particles of the medium will be perpendicular to the direction of propagation of wave.


From figure, we can see $x-y$ plane is perpendicular to $z-$ axis. Hence, particles can oscillate in $x-y$ plane when a transverse wave propagates along $z-$ axis.
