Today's post shall be short and sweet.
Anyway, the question is:
Why is the red at the top of the spectrum of colours, and the violet at the bottom?
I came across a website that states that instead of having the red at the top, the red is at the bottom and the violet is at the top. This pictures shows how.
But in any case, the same website also states that the wavelength and frequency of light we see, also influences the colour we see. The seven colours of the spectrum all have varying wavelengths and frequencies. Red is at the lower end of the spectrum and has a higher wavelength but lower frequency to that of Violet. Whereas Violet, located at the top end of the spectrum, has a lower wavelength and higher frequency.
Frequency
The frequency of a wave is determined by the number of complete waves, or wavelengths, that pass a given point each second.
However, another websites says that "Red light has the longest wavelength in the visible spectrum and therefore reflects the least. It is found at the top of the visible spectrum. Violet light has the shortest wavelength in the visible spectrum and therefore reflects the most. It is seen at the bottom of the spectrum." So Basically, it is because of the length of the wavelength in this website, and both the length of the wavelength and frequency in the first website, that explains why the red is at the top and violet is at the bottom, vice versa.
And, another website also stated that red has the longest rays and in this case, violet has the shortest rays, so tah-dahs!
Hope it is not confusing.
