What color line from a spectrum represents a bigger change in energy a purple line or a red line?

In the visible spectrum, a purple line represents a higher energy photon compared to a red line. This is because purple light has a shorter wavelength and higher frequency, which corresponds to greater energy according to the equation (E = hf), where (E) is energy, (h) is Planck's constant, and (f) is frequency. Therefore, a change from red to purple indicates a bigger change in energy.
