SUMMARY

The visible light spectrum is not strictly confined to the commonly cited range of 400-800nm. Instead, the short-wave limit is more accurately defined at 430nm, while the long-wave limit can extend to 690nm. Some discussions suggest a broader range of 350nm to 750nm, indicating variability in definitions across different sources. This inconsistency highlights the lack of universally accepted boundaries for the visible spectrum.

PREREQUISITES
  • Understanding of electromagnetic radiation
  • Familiarity with wavelength measurements
  • Knowledge of light spectrum classification
  • Basic principles of optics
NEXT STEPS
  • Research the electromagnetic spectrum and its classifications
  • Explore the effects of wavelength on color perception
  • Study the properties of light in the 350-750nm range
  • Investigate the implications of varying definitions in scientific literature
USEFUL FOR

Students of physics, optical engineers, and anyone interested in the nuances of light and its measurement will benefit from this discussion.

In spectrum of EM radiation domain of visible light isn't strictly limited. In books is usually given from 400-800nm. But for visible domain short-wave limit is \lambda=430nm, and long-wave limit is \lambda=690nm? Why we say then that the boundaries are 400-800nm?

Yes it differs from book to book...the boundaries are not very strict..i say the visible range is from 350 nm to 750 nm.
 
If you google "wavelength of light" you will get a slew of results and they will all be slightly different. Lower limit 350 - 400, upper limit 690 - 750.
