Are you sure it’s 300 mm?
If it’s 300 mm then here is the answer
Frequency = Velocity of light / Wavelength of light
= (3 × 10^8 m/s) / (300 × 10^-3 m)
= 10^9 Hz
= 1 gigahertz

If it’s 300 nm then answer is
Frequency = Velocity of light / Wavelength of light
= (3 × 10^8 m/s) / (300 × 10^-9 m)
= 10^15 Hz
= 1 petahertz
