Question

the diagram represents a snapshot in time of a wave traveling through a slinky. use the background grid to determine the wavelength and the amplitude of the wave. each square measures 1-cm along its edge. wavelength (cm): tap here amplitude (cm): tap here

Explanation:

Step1: Determine Wavelength

Wavelength is the distance between two consecutive identical points (e.g., peaks or troughs) on a wave. Looking at the grid, from one peak to the next peak, we count the number of 1 - cm squares. The distance between two adjacent peaks spans 8 squares (each 1 cm), so wavelength = 8 cm.

Step2: Determine Amplitude

Amplitude is the maximum displacement from the equilibrium (middle) line to a peak (or trough). From the middle line to a peak, we count the number of 1 - cm squares. This distance is 2 squares, so amplitude = 2 cm.

Answer:

Wavelength: 8 cm, Amplitude: 2 cm
