Question

What is the visible wavelength range of visible light?

Answer 1

Although all electromagnetic radiation is light, we can only perceive a small amount of it, which we refer to as visible light.
Our eyes have cone-shaped cells that operate as receivers for wavelengths in this limited band of the spectrum.
Other parts of the spectrum have wavelengths that are either too large or too small and energetic for our biological constraints.

Complete step by step answer:
The visible light spectrum is the portion of the electromagnetic spectrum that can be seen with the naked eye. This band of wavelengths is referred to as visible light. The human eye can detect wavelengths ranging from $380$ to $700$ nanometers in most cases.
Because each hue is a different wavelength, when the whole spectrum of visible light passes through a prism, the wavelengths divide into the rainbow colors. Violet has the shortest wavelength (about $380$nanometers), whereas red has the longest (about $700$ nanometers).

Note: The Sun is the primary source of visible light waves that reach human eyes. In visible light, the corona, the outermost layer of the Sun's atmosphere, may be seen. However, because the brilliant photosphere overwhelms it, it can only be seen during a total solar eclipse.
As objects heat up, they emit energy with shorter wavelengths, changing color in front of our sight. As a blow torch's flame is adjusted to burn hotter, it changes color from reddish to bluish. Similarly, the color of stars indicates their warmth to scientists.
A prism bends visible light, and each color refracts at a slightly different angle depending on the wavelength of the color, according to Isaac Newton's experiment in $1665$ .
