Study the scenario.

Avery shakes one end of a spring side to side. The wave travels from her end of the spring to the opposite end of the spring.

Which of the following choices best describes the type of wave generated in the spring?

It is a transverse wave. While Avery moves the spring side to side, the wave moves forward. The two motions are parallel.
It is a longitudinal wave. While Avery moves the spring side to side, the wave moves forward. The two motions are parallel.
It is a transverse wave. While Avery moves the spring side to side, the wave moves forward. The two motions are perpendicular.
It is a longitudinal wave. While Avery moves the spring side to side, the wave moves forward. The two motions are perpendicular.

a? Or c?

If you shake a spring side to side the particles being displaced is from left to right. But the energy is going towards the other end essentially a straight line. So that would be perpendicular. The 3rd choice transverse waves, motion is perpendicular.

Oh, thank you for explaining! I really appreciate it

I'd have to go with c. It is a transverse wave. While Avery moves the spring side to side, the wave moves forward. The two motions are perpendicular. Just like when you're in a dance battle and do the worm, your body moves horizontally while the crowd's opinion of your dance moves goes vertically. Perpendicular motions for the win!

The correct option is c: "It is a transverse wave. While Avery moves the spring side to side, the wave moves forward. The two motions are perpendicular."

To determine the type of wave generated in the spring, it is important to understand the characteristics of transverse and longitudinal waves.

A transverse wave is characterized by the particles of the medium (in this case, the spring) moving perpendicular to the direction of wave propagation. In other words, the motion of the medium and the motion of the wave are perpendicular to each other. In this scenario, as Avery shakes one end of the spring side to side, the wave generated in the spring also moves forward, perpendicular to the motion of the spring. This aligns with the definition of a transverse wave.

On the other hand, a longitudinal wave is characterized by the particles of the medium moving parallel to the direction of wave propagation. This means that the motion of the medium and the motion of the wave are parallel to each other. In this scenario, while Avery moves the spring side to side, if the wave generated also moved forward in the same direction, parallel to the motion of the spring, it would be a longitudinal wave. However, since the wave moves perpendicular to the motion of the spring, it does not fit the definition of a longitudinal wave.

Therefore, based on the description provided, the type of wave generated in the spring is a transverse wave, making option c the correct choice.

Im confused...

Transverse are perpendicular. Longitude are parallel.

the the displacement of the spring parallel or perpendicular

... to the travel of the wave?
