Sound? Longitudinal

Light? Transverse

Surface water waves are a little complicated Surface water waves are a little complicated. They are a combination of transverse and longitudinal. So are surface earthquake waves.

Waves in which the medium vibrates perpendicular to the direction the wave travels? Transverse

Waves in which the medium vibrates parallel to the direction the wave travels? Longitudinal

Medium vibrates up and down as the wave travels to the right Medium vibrates up and down as the wave travels to the right? Transverse

Medium vibrates left and right as the wave travels to the right Medium vibrates left and right as the wave travels to the right? Longitudinal

Medium vibrates east and west as the wave travels to the north Medium vibrates east and west as the wave travels to the north? Transverse

Medium vibrates up and down as the wave travels to the north Medium vibrates up and down as the wave travels to the north? Transverse

Medium vibrates north and south as the wave travels to the north Medium vibrates north and south as the wave travels to the north? Longitudinal

Waves in which groups of molecules in the air are alternately compressed and expanded? Longitudinal (sound)

Waves in which the electric and magnetic fields alternately get stronger then weaker? Transverse (light, a.k.a. electromagnetic waves)

Radio waves? Transverse (light, a.k.a. electromagnetic waves)

Ultraviolet waves? Transverse (light, a.k.a. electromagnetic waves)

X-rays (x-ray waves)? Transverse (light, a.k.a. electromagnetic waves)

Infrared waves? Transverse (light, a.k.a. electromagnetic waves)

Sound waves? Longitudinal

Transverse

Longitudinal

Careful! The top part is a graph of air pressure as the wave travels to the right. ? Longitudinal! It is a sound wave. The air molecules move right-left as the wave moves to the right.
