describing the electromagnetic spectrum\nwhich side of the electromagnetic spectrum has shorter…

Brief Explanations:

In the visible - light part of the electromagnetic spectrum, blue light has shorter wavelengths, higher frequencies, and higher energy compared to red light. The energy of electromagnetic radiation is directly proportional to its frequency and inversely proportional to its wavelength ($E = h\nu=\frac{hc}{\lambda}$, where $E$ is energy, $h$ is Planck's constant, $\nu$ is frequency, $c$ is the speed of light, and $\lambda$ is wavelength).

Answer:

For shorter wavelengths: blue For higher energy: blue For higher frequency: blue
