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 crests (or troughs). Looking at the grid, from one crest to the next, we count the number of 1 - cm squares. Let's take two consecutive crests. The horizontal distance between them: each square is 1 cm. Counting the squares between two crests, we see that it spans 4 squares. So wavelength = 4 cm.

Step2: Determine Amplitude

Amplitude is the maximum displacement from the equilibrium (the middle line) to a crest (or trough). From the equilibrium line (the gray line) to a crest, we count the number of 1 - cm squares. The vertical distance from the equilibrium to a crest is 1 square. So amplitude = 1 cm.

Answer:

Wavelength: 4 cm, Amplitude: 1 cm
