The wavelength of a beam of red light is 6760 pm. What is its wavelength in angstroms (Å) is 67.60 A
in this case the wavelength of the beam of read light is 6760pm, so,6760 pm X 10^-12m/ 1pm = 6760 X 10^-12m now to convert it into angstroms 6760 X 10^-12m / 1^-10 m = 6760 X 10^-2 = 67.60 A The region of the electromagnetic spectrum that the human eye can see is known as the visible light spectrum. This group of wavelengths is more commonly referred to as visible light. The range of wavelengths that the human eye can typically see is from 380 to 700 nanometers. a length in the SI system equivalent to 10^-12 meters;
