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