Question

mission wm1: nature and categories of waves
the diagrams below depict various wave patterns in a slinky. the arrows represent potential direction of hand movements for the creation of such patterns. which diagram - a, b, c, or d - represents the appropriate hand movements and patterns for a transverse wave?

Explanation:

Step1: Recall transverse wave definition

A transverse wave has oscillations (hand movement) perpendicular to wave propagation (slinky pattern direction).

Step2: Analyze each diagram

• Diagram A: Hand movement is diagonal, not purely perpendicular.
• Diagram B: Hand moves up - down (perpendicular), wave pattern is transverse (oscillations perpendicular to propagation).
• Diagram C: Hand moves up - down but slinky is compressed (longitudinal wave pattern).
• Diagram D: Hand moves horizontally (parallel to slinky), longitudinal wave.

Answer:

B. Diagram B
