In free space (or air) o= o(k)= c.k. For infrared light (2=1.5 um) calculate its frequency, f in cycles/sec= Hertz and argue that for wide band communication you prefer to use a infrared laser light and optical fiber link rather than a f-10 GHz microwave link.

Expert Solution
Step 1

.                             SOLUTION 

GIVEN

  For Infrared Light Wavelength λ

  λ = 1.5 μm 

Calculate Frequency f

WE KNOW 

f =  c/λ

Where 

      c= Speed of Light

      c= 3×108 m/sec

=> f = (3×108)/(1.5×10-6) = 2×108×106 Hz

=> f = 2×1014 Hz or cycles/sec

                          ANSWER

  FREQUENCY OF INFRARED LIGHT IS

               f = 2×1014 Hertz
