Region of the electromagnetic spectrum extending from about \(400\ \text{nm}\) to \(760\ \text{nm}\). This is the @W06659@ region to which the human eye is sensitive. There are no precise limits for the spectral range of visible radiation since they depend upon the amount of @R05046@ reaching the retina and on the responsivity of the observer.
