Question 3
If power is 100 mWatts and beam area is 2 cm2, what is the intensity?
P µ A2 A = Max – Mean I = Power / beam area
Mean = (Maximum + Minimum)/2 Mean = Min + Amp
Mean = max – amp Min = Mean – Amp
Max = Amp + Mean
P µ A2 A = Max – Mean I = Power / beam area
Mean = (Maximum + Minimum)/2 Mean = Min + Amp
Mean = max – amp Min = Mean – Amp
Max = Amp + Mean
