6 xx10^14 Hz

Explanation:

flamda=c
f=c/lamda= (3xx10^8m/s)/(500xx10^-9)=6 xx10^14 Hz

6.67xx10^14Hz

Explanation:

Wavelength formula is C=λf or λ=C/f or f = C/λ,
so Frequency = Velocity divided by wavelength, where
C is the velocity, which is the speed of light: 3.00 × 10^8 m/sec
λ is the wavelength in meters
f is the frequency in Hertz (cycles per second)
f = 3.00 × 10^8 m/sec /4.5 xx 10^(-7) m = 6.67xx10^14Hz
