Solution
The correct option is B Slinky Answer is B. In a transverse wave, the motion of the medium is perpendicular to the motion of the wave. To clarify, in a water wave, the actual water molecules move up and down while the wave moves horizontally. Longitudinal waves, in contrast, are waves in which the medium moves back and forth in the same direction as the motion of the wave. Sound waves are of this type. For example, when we lay the slinky down on the ground and push it back and forth lengthwise it creates longitudinal waves.To make transverse waves, we shake the slinky back and forth perpendicular to the length. Hence, a slinky can be used to produce longitudinal waves as well as transverse waves under different conditions.
