Okay, so in figure 2 .7, which of the following has the lowest energy? so this figure right here is figure 2 .7.
00:11
And this is asking which one of the following has the lowest energy? invisible light, x -ray, ultraviolet ray, or infrared ray.
00:23
So to have the lowest energy, to have low of low, energy, it would equal you have to have a greater wavelength.
00:49
So the further down you are on the spectrum, you have the lower energy, and the shorter your wavelength is, you have greater energy.
01:03
So this is high energy, and this is low energy.
01:10
So as we can see, invisible light would range somewhere around 400 nanometers...
