Question

choose the correct answer. which wave has the highest energy? a b

Explanation:

Step1: Recall the relationship between wave energy and frequency/wavelength

The energy of a wave is related to its frequency ($f$) and wavelength ($\lambda$) by the formula $E = hf$ (where $h$ is Planck's constant) and $c=\lambda f$ (where $c$ is the speed of light). Higher - frequency (shorter - wavelength) waves have higher energy. Visually, a wave with a shorter wavelength (more oscillations in a given space) has higher frequency.

Step2: Compare waves A and B

Wave A has a shorter wavelength (more oscillations in the same horizontal space) compared to wave B. Since $E = hf$ and $f=\frac{c}{\lambda}$, a shorter wavelength ($\lambda$) implies a higher frequency ($f$), and thus higher energy.

Answer:

A
