  • Wavelength($\lambda$)=685nm

[tex]\\ \sf\bull\longmapsto \lambda=\dfrac{c}{v}[/tex]

[tex]\\ \sf\bull\longmapsto v=\dfrac{c}{\lambda}[/tex]

[tex]\\ \sf\bull\longmapsto v=\dfrac{3\times 10^8}{685\times 10^{-9}m}[/tex]

[tex]\\ \sf\bull\longmapsto v=0.00437\times 10^{17}Hz[/tex]

[tex]\\ \sf\bull\longmapsto v=4.3\times 10^{14}Hz[/tex]
