Answer:
Visible ligth correspond to wavelengths between 390 and 800 nanometers (nm)
Explanation:
The electromagnetic spectrum is the wide spectrum of light. We separate it in different regions with different wavelengths and assign a name to each of those regions: X-ray, gamma ray, visible light, ultraviolet, etc. Most of the electromagnetic spectrum is invisible for human’s eye but there is a small region of visible light that include wavelengths between 390 nm (violet) and 800 nm (red), in this region there are all the colors human's eye can see.
The wavelength of the electromagnetic spectrum that corresponds to the visible light is 750 nm --- 400 nm.
Electromagnetic spectrum consists of radiations arranged in order of frequencies and wavelengths.
The arrangement of electromagnetic spectrum in order of increasing wavelength is written as;
- Gamma rays ---- < 1 pm
- X rays -------- 1 nm - 1 pm
- Ultra violet rays ---- 400 nm - 1 nm
- Visible light ------ 750 nm - 400 nm
- Infrared ---------- 2.5 μm - 750 μm
- microwaves ------- 25 μm - 2.5 μm
- radio waves ----- > 1mm
Thus, we can conclude that the wavelength of the electromagnetic spectrum that corresponds to the visible light is 750 nm --- 400 nm.
