Question

1. sketch a wave with low frequency and low energy. 15. label the diagram below in terms of frequency, wavelength, and energy.

Explanation:

Step1: Recall wave - property relationships

The frequency ($f$), wavelength ($\lambda$) and energy ($E$) of a wave are related by $c = f\lambda$ (where $c$ is the speed of light in a vacuum) and $E=hf$ (where $h$ is Planck's constant). For a low - frequency wave, from $c = f\lambda$, the wavelength is long (since $c$ is constant), and from $E = hf$, the energy is low.

Step2: Sketch the wave

Draw a wave with a long wavelength. The wave should have a relatively small number of cycles over a given distance, indicating low frequency. The amplitude of the wave can be moderate. Mark the wavelength as $\lambda$ (a long distance between two consecutive crests or troughs), label the frequency as $f$ (with a note indicating it is low), and label the energy as $E$ (with a note indicating it is low).

Answer:

Sketch a wave with a long wavelength (a large distance between consecutive crests or troughs), label the frequency as "low frequency", and label the energy as "low energy".
