¿Cuál es el rango de frecuencias comprendido entre las longitudes de onda de 220 nm, 350 nm, 800 mn y 3500 nm? ¿A qué banda del espectro electromagnético corresponden esas
frecuencias?

f1 = 1.36*10^15 Hz

f2 = 8.57*10^14 Hz

f3 = 3.75*10^14 Hz

f4 = 8.57*10^13 Hz

Explanation:

To know which are the frequency ranges of the wavelengths you use the following formula:

c: speed of light = 3*10^8m/s

λ: wavelength = 220nm, 350nm, 800nm, 3500nm

f: frequency of the wave

You calculate f for each wavelength, furthermore, you add the kind of electromagnetic wave:

λ1 = 220nm = 220*10^-9 m

  ULTRAVIOLET

λ2 = 350nm = 350*10^-9 m

  VISIBLE LIGHT

λ3 = 800nm = 350*10^-9 m

  INFRARED    

λ4 = 3500nm = 350*10^-9 m
