The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light.A typical human eye will respond to wavelengths from about 380 to 740 nanometers. In terms of frequency, this corresponds to a band in the vicinity of 430–770 THz.
Yellow is the color between orange and green on the spectrum of visible light.It is evoked by light with a dominant wavelength of roughly 570–590 nm.It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity.
The range of wavelengths (400 - 700 nm) of visible light is centrally located in the electromagnetic spectrum (Fig. 1). Infrared and radio waves are at the long wavelength side while ultraviolet (UV), x-rays and gamma rays lie at the short wavelength side of the electromagnetic spectrum.
The full range of wavelengths for light is called the "electromagnetic spectrum." The image and table below show which wavelength ranges in the electromagnetic spectrum correspond to which types of light.
Light outside this range may be visible to other organisms but cannot be perceived by the human eye. Colors of light that correspond to narrow wavelength bands (monochromatic light) are the pure spectral colors learned using the ROYGBIV acronym: red, orange, yellow, green, blue, indigo, and violet.
The remaining light will then assume the complementary color to the wavelength(s) absorbed. This relationship is demonstrated by the color wheel shown on the right. Here, complementary colors are diametrically opposite each other. Thus, absorption of 420-430 nm light renders a substance yellow, and absorption of 500-520 nm light makes it red.

You have named the colors of the visible spectrum. It was discovered as such by Sir Isaac Newton when he held a triangular glass prism in a sunbeam and it split the white light of the sun into a fan of colors we now call the visible spectrum. The ...
The wavelength of yellow light is in the range of 577-597 nanometers. Human eyes are compatible with a small region of the electromagnetic spectrum.... See full answer below.
What we see as white light is in fact a mixture of light of different wavelengths. We see light with wavelengths in the range 390nm - 700nm or so. Each specific wavelength corresponds to a pure colour ranging from violet to red. White light is a mixture of colours. One of my favourite puzzle questions is "Why does a combination of red light and green light make yellow light?"
