Question

Particles in a __________ wave move in an elliptical or circular motion. question 4 options: sound longitudinal transverse surface

Answer 1

Answer: The correct answer is "surface".

Step-by-step explanation:

The particles oscillate to the parallel to the direction of the energy transportation in the longitudinal wave. For example, sound wave.

Transverse wave: The particles oscillate to the perpendicular to the direction of the energy transportation. For example, light wave.

Surface wave: This wave is neither transverse wave or longitudinal wave. It moves both parallel and perpendicular to the direction of the propagation of the wave. It moves in a circular motion to the direction of the energy transportation.

Therefore, Particles in a surface wave move in an elliptical or circular motion.

Answer 2

The sentence can be completed as follows:
"Particles in a SURFACE wave move in an elliptical or circular motion". So Answer D is the correct one.

Explanation: surface waves are waves that move in circular or elliptical motion at the interface between two mediums (for example, between water and air). An example of surface wave is the wave obtained when you throw a stone in the water: the wave produced when the stone touches the water is a surface wave, that moves with concentrical circles around the source.
