Final answer:
The visible light spectrum can be represented by a diagram called the 'Color Spectrum.' Light waves of yellow, blue, and red can be ordered by wavelength from blue (shortest) to red (longest) and by frequency from red (lowest) to blue (highest). Red, green, and blue light mix to create the full range of colors seen on RGB displays.
Step-by-step explanation:
To sketch and color the visible light spectrum with corresponding wavelengths, we would draw a band of colors in the order of red, orange, yellow, green, blue, indigo, and violet, with the color red having the longest wavelength and violet having the shortest wavelength. The diagram that should be referred to for this task is called the Color Spectrum. The wavelengths of the visible spectrum range approximately from 700 nm (nanometers) for red light to around 400 nm for violet light.
For the colors of light mentioned - yellow, blue, and red - Part A requires us to order the light waves according to wavelength from shortest to longest. The correct order would be blue, yellow, then red. Part B requires us to order these colors according to frequency from lowest to highest frequency, which would be the reverse order: red, yellow, then blue.
The Color Vision concept is essential for understanding how different wavelengths of light are perceived by the human eye and consists of a broad range of hues from red to violet. In the context of RGB color displays, red, green, and blue are mixed to produce the colors seen on our screens. To determine the approximate wavelength of each of these primary colors, we would refer to a visible light spectrum, noting that red light has the longest wavelength, green is in the middle, and blue has the shortest wavelength within the visible range.
