the diagram represents a snapshot in time of a wave traveling through a slinky. use the background grid to determine the wavelength of the wave. each square measures 1-cm along its edge.
Answer
Explanation:
Step1: Recall Wavelength Definition
Wavelength is the distance between two consecutive identical points (e.g., compressions, rarefactions) on a wave. For a longitudinal wave (like in a Slinky), we can use the grid (1 cm per square) to measure this distance.
Step2: Identify Consecutive Points
Looking at the Slinky wave diagram, find two consecutive compressions (the darker red regions). Count the number of squares between their start (or center) points. From one compression to the next, we observe that the distance spans 3 grid squares. Since each square is 1 cm, the wavelength is ( 3 \times 1,\text{cm} = 3.0,\text{cm} ).
Answer:
( 3.0 )
