Why are the graphs for the distribution of light from the Sun as a function of (a) frequency and (b) wavelength not exactly reversed? ( www.wtamu.edu )

I thought that the frequency of light was directly inverse to the wavelength by a constant. In other words, I assumed that graphing the frequency of light as a function of wavelength would be a straight inverse line. Because of that, the graphs for the distribution of light from the sun as functions of frequency and wavelength...

The frequency is not directly proportional to the wavelength - it’s inversely proportional: en.wikipedia.org/…/Proportionality_(mathematics)#…

Think of this as this: The wavelength is the distance that light travels during one wave i.e. cycle. Light propagates with the speed of light, so the smaller the wavelength, it means the frequency must increase. If the wavelength gets two times lower, the frequency increases two times. If wavelength approaches 0, then frequency starts growing very quickly, approaching infinity.

The plot is not a straight line but a hyperbola.
