Janiya Townsend · Answer 1

Tyrone is basically analyzing a low frequency because the human the human eyes are sensitive to green colour which has a wavelength of 500nm that is close to that of 486nm

Since frequency is inversely proportional to the wavelength from wave equation

v = f λ.

f = v / λ

So, he is basically analyzing the highest wavelength which is 650nm.

Thus, we can conclude that the colours near the red are of the same wavelength as 656nm.
