The length of the colour attribute is 6 characters.
<h3>What is a colour attribute?</h3>
Each colour has a distinct look based on three essential characteristics: hue, chroma (saturation), and value (lightness). It's critical to use all three of these properties when describing colour to appropriately identify it and distinguish it from others.
<h3>What is the use of colour attributes?</h3>

The hierarchy of need was developed by Maslow. The pyramid is a motivational theory in psychology that argues that people is seeking to meet successively higher needs. The base of the pyramid is for the physiological needs to safety, belongingness, esteem, and finaly self-actualization.
To solve this problem it is necessary to apply the concepts related to wavelength as a function of frequency and speed, as well as to determine the wavelength as a function of length.
From the harmonic vibration generated we know that the total length of the string will be equivalent to a half of the wavelength, that is

Where,
Wavelength
Therefore the wavelength for us would be,

From the relationship of speed, frequency and wavelength we know that



Therefore the speed of the wave is 232.75m/s
