Question

Un apuntador de láser rojo emite una luz con longitud de onda de 650 nm
¿cual es la frecuencia de la luz?

Answer 1

λ = 650 nm = 6.5×10−7 m

λ = 650 nm = 6.5×10−7 mc = 3×108 m

λ = 650 nm = 6.5×10−7 mc = 3×108 mν = 4.6153846154×1014 Hz

λ = 650 nm = 6.5×10−7 mc = 3×108 mν = 4.6153846154×1014 HzE=nhν

λ = 650 nm = 6.5×10−7 mc = 3×108 mν = 4.6153846154×1014 HzE=nhν E = (6.022×1023)(6.6261×10−34)(4.6153846×1014)

λ = 650 nm = 6.5×10−7 mc = 3×108 mν = 4.6153846154×1014 HzE=nhν E = (6.022×1023)(6.6261×10−34)(4.6153846×1014) E = 184.164.12505 J

λ = 650 nm = 6.5×10−7 mc = 3×108 mν = 4.6153846154×1014 HzE=nhν E = (6.022×1023)(6.6261×10−34)(4.6153846×1014) E = 184.164.12505 JE = 184.164123 kJ
