How are longitude and transverse waves similar a. the particles vibrate perpendicular to the wave motion b. no similarities c. they transfer energy through a medium d. the particles vibrate parallel to the wave motion need !

The correct answer is: C. They transfer energy through a medium  

There are different types of waves, depending on their medium: electromagnetic (energy is transferred through vibrations of electric and magnetic field), sound (energy is transferred through vibration of air particles), water (energy is transferred through the vibration of the water particles).

Longitudinal waves - particles vibrate parallel to the direction of wave propagation

Transverse wave -particles vibrate perpendicular to the direction of wave propagation.
