Question

use the figure below to answer the question. figure: ac different waves looking at the figure, how can wave d be compared to the other waves? wave d has the highest frequency. wave d has the longest wavelength. wave d has the least energy. wave d is equal in frequency, wavelength, and energy to the other waves.

Explanation:

Step1: Recall wave - property relationships

Frequency is the number of waves per unit time. Wavelength is the distance between two consecutive crests or troughs. Energy of a wave is related to its frequency ($E = hf$, where $h$ is Planck's constant).

Step2: Analyze the figure

Wave D has more wave - cycles in the same amount of space compared to waves A, B, and C. So, it has a higher frequency. Higher frequency means shorter wavelength (since $v=\lambda f$ and for a given medium, the wave speed $v$ is constant). Also, higher frequency implies higher energy.

Answer:

Wave D has the highest frequency.
