4) 6.7x10^14Hz6.7x1014Hz

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 × 10^83.00×108 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 x 10^(-7) m = 6.7x10^14Hzf=3.00×108msec/4.5x10−7m=6.7x1014Hz
