  • The wavelength of the red light in "nanometer" is 7× [tex]10^{2}[/tex]

  • Wavelength is given as : [tex]7*10^{-7}[/tex] meter

  • 1 nanometer =[tex]10^{-9}[/tex] ( meter)

  • Let X= value of the wavelength in nanometer.

1 nanometer  = [tex]10^{-9}[/tex] meter

X nanometer = 7×  [tex]10^{-7}[/tex] meter

  • If we Cross multiply

  • X nanometer =   (  [tex]\frac{ 7*10^{-7} }{ 10^{-9} }[/tex]   )

  • X= 7×[tex]10^{2}[/tex] nanometer

Therefore, the wavelength in "nanometer" is 7×[tex]10^{2}[/tex]
