The wavelength of infrared light is 1000 nm. What is the frequency in Hz? c=3.00x10^8m/s

ans choices are
3.0x10^14
4.0x10^15
1.0x10^13
2.0x10^14
4.0x10^14

Respuesta :

[tex]\\ \tt\Rrightarrow \nu=\dfrac{c}{\lambda}[/tex]

  • v is frequency
  • lambda is wavelength

[tex]\\ \tt\Rrightarrow \nu=\dfrac{3\times 10^8}{1000\times 10^{-9}}[/tex]

[tex]\\ \tt\Rrightarrow \nu=0.003\times 10^{17}s^{-1}[/tex]

[tex]\\ \tt\Rrightarrow \nu=3\times 10^{14}Hz[/tex]
