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
