Which of the following wavelengths corresponds to the color yellow in the visible spectrum?

The wavelength that corresponds to the color yellow in the visible spectrum is approximately 570 nanometers. In the context of visible light, the spectrum ranges from about 380 nm (violet) to around 750 nm (red). Each color has a specific range of wavelengths associated with it.

Yellow light typically falls between the wavelengths of about 570 nm to 590 nm. Thus, the choice indicating 570 nm accurately aligns with this range, making it representative of the color yellow.

In contrast, the other options represent different colors of light: 480 nm corresponds to blue light, 400 nm corresponds to violet or blue-violet light, and 620 nm corresponds to red light. Understanding the relationship between wavelengths and color perception is essential in fields such as optics, visual arts, and skin physiology, influencing how treatments and products are developed based on color characteristics.
