$ν = 6.246 \times 10^{14} H z = 624.6 T H z$ $nu=6.246xx10^14 Hz=624.6 THz$

Explanation:

$Wavelength of Light$ $"Wavelength of Light"$ $λ = 4.8 \times 10^{2} n m$ $lamda=4.8xx10^2nm$
$λ = 4.8 \times 10^{2} \times 10^{- 9} m = 4.8 \times 10^{- 7} m$ $lamda=4.8xx10^2xx10^-9m=4.8xx10^-7m$

Relation between frequency of light and wavelength is
$ν = \frac{c}{λ}$ $nu=c/lamda$
$ν = Frequency of light$ $nu="Frequency of light"$
$c = speed of light$ $c="speed of light"$

$ν = \frac{3 \times 10^{8}}{4.8 \times 10^{- 7}} = \frac{3}{4.8} \times 10^{15}$ $nu=(3xx10^8)/(4.8xx10^-7)=3/4.8xx10^15$
$ν = 6.246 \times 10^{14} H z = 624.6 T H z$ $nu=6.246xx10^14 Hz=624.6 THz$
