Which of the following wavelengths corresponds to the visible light range?

The visible light range is defined as the portion of the electromagnetic spectrum that is visible to the human eye, typically encompassing wavelengths from approximately 400 nanometers (nm) to 700 nanometers (nm). This range includes all the colors perceived by humans, from violet at the lower end of the spectrum (around 400 nm) to red at the upper end (around 700 nm).

Choosing the correct range is essential in various applications, including laser therapy, as different wavelengths can have different effects on biological tissues. Wavelengths outside this range, such as those listed in the other options, either fall into ultraviolet or infrared categories, which are not visible to the human eye and serve different purposes in scientific and medical contexts. Therefore, the range of 400 nm to 700 nm is recognized as the visible spectrum, making it the correct answer.
