    Answer:

    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=\lambda f\\\\f=\frac{c}{\lambda}

    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

    f=\frac{3*10^8m/s}{220*10^{-9}m}=1.36*10^{15}Hz   ULTRAVIOLET

    λ2 = 350nm = 350*10^-9 m

    f=\frac{3*10^8m/s}{350*10^{-9}m}=8.57*10^{14}Hz   VISIBLE LIGHT

    λ3 = 800nm = 350*10^-9 m

    f=\frac{3*10^8m/s}{800*10^{-9}m}=3.75*10^{14}Hz   INFRARED    

    λ4 = 3500nm = 350*10^-9 m

    f=\frac{3*10^8m/s}{3500*10^{-9}m}=8.57*10^{13}Hz   MICROWAVE – INFRARED
