Question

1. the diagram to the left shows models of four different electromagnetic waves. how can wave a be compared to the other waves? wave a has the shortest wavelength, lowest frequency, and lowest energy wave a has the longest wavelength, lowest frequency, and lowest energy wave a has the shortest wavelength, highest frequency, and greatest energy wave a has the longest wavelength, highest frequency, and greatest energy

Explanation:

Step1: Recall wave - property relationships

The relationship between wavelength ($\lambda$), frequency ($f$), and energy ($E$) for electromagnetic waves is given by $c = \lambda f$ (where $c$ is the speed of light in a vacuum) and $E=hf$ (where $h$ is Planck's constant). From $c = \lambda f$, when $\lambda$ is large, $f$ is small. From $E = hf$, when $f$ is small, $E$ is small. So, a long - wavelength wave has a low frequency and low energy, and a short - wavelength wave has a high frequency and high energy.

Answer:

Wave A has the longest wavelength, lowest frequency, and lowest energy.
