>There is no concept of frequency in the color red

>>Red light has relatively long waves, around 700 nm long

Those 700 nm or ~428274 gigahertz is the frequency of red (as a human eye normally sees color) light waves.

>>Frequency is a measure of how often a given event repeats itself. In physics, it is commonly used to describe waves.

>>Frequency is the number of occurrences of a repeating event per unit of time

You can scroll down and you will find "Light" and "Sound"

This is "our" visible spectrum, to the left increased frequency to the right increased wavelength:

>the concept of "waves" and come to the conclusion that these are waves you are looking at.

It's not a concept but:

>>a wave is a disturbance or variation which travels through a medium.

And stop with you wannabe philosophical BS, it sounds just uneducated even borderline clownish.
