Answer:

The frequency of infrared light of 1.0 x [tex]10^{-4}[/tex] is 3 THz

Explanation:

Given

The wavelength (λ) of Infrared light = 1.0 x [tex]10^{-4}[/tex]

To find:

Frequency (ν) of the infrared light

We know that the wavelength and frequency are inversely proportionaly, which derives an equation:

            c = νλ

c is velocity of light = 3 x [tex]10^{8}[/tex] m[tex]s^{-1}[/tex]

Hence Frequency (ν) of the infrared light is given by

ν = c/λ

  = (3 x [tex]10^{8}[/tex] )/ (1.0 x [tex]10^{-4}[/tex])

  = 3 x [tex]10^{12}[/tex]Hz

  = 3 THz (Terra Hertz)

Hence the frequency of infrared light of 1.0 x [tex]10^{-4}[/tex] is 3 THz
