Question

1. sketch the diagram of a wave and label the amplitude and wavelength

Explanation:

A wave diagram typically has a sinusoidal shape. The amplitude is the maximum displacement from the equilibrium position (the mid - line of the wave). The wavelength is the distance between two consecutive points that are in - phase (e.g., from crest to crest or trough to trough).

Answer:

Draw a sinusoidal curve. Mark the vertical distance from the mid - line to the crest (or trough) as the amplitude. Mark the horizontal distance between two consecutive crests (or two consecutive troughs) as the wavelength.
