Question

1. sketch a wave with low frequency and low energy.

Explanation:

A wave with low - frequency has fewer cycles per unit time. Low - energy implies a small amplitude as energy is related to amplitude squared. For a visual sketch, draw a smooth, undulating curve with wide - spaced peaks and troughs (indicating low frequency) and relatively small height differences between the peaks and troughs (indicating low energy).

Answer:

Draw a smooth curve with widely - spaced peaks and troughs and small vertical displacements from the equilibrium position.
