Hoorcollege Analytische Technieken
Formules en rekenvoorbeelden

Deze rekenvoorbeelden komen o.a. uit het hoorcollege, maar staan niet in de
kennisclips. In blauw zijn de rekenvoorbeelden die bij de toets stof horen
(beheersen), in groen de verdiepende opdrachten. Deze horen niet bij de toetsstof,
maar dienen voor een beter begrip van een onderwerp of de toepassing daarvan.

• voorbeeld omrekenen van golflengte naar frequentie
Stel λ = 200 nm = 2,00 x 10-7 m
dan  = (2,998 x 10 8) m/s /(2,00 x 10 -7) m= 1,50 x 10 15 Hz

• voorbeeld berekening van frequentie naar energie
Stel  = 1,50 x 10 15 Hz (s-1)
dan ΔE = (6,626 x 10-34) Js x (1,50 x 10 15) s-1= 9,94 x 10 -19 J
