Question

A wave travels through a medium and displaces the particles perpendicular to the direction in which the wave is traveling. This type of wave is a:

transverse wave because of the direction that the particles are being displaced as the wave travels

longitudinal wave because of the way the particles are displaced as the wave passes through

longitudinal wave because it moves forward through a medium causing the particles to vibrate

transverse wave because it is not traveling in a vacuum and the particles are moving

Answer 1

Transverse because displacement of wave at any point is perpendicular to the direction of the wave (E/M or light wave)

Sound waves are examples of longitudinal waves because the particle displacement is in the same direction as the wave travels

Sound waves need a medium (air) for transmittal, light waves do not
