How do I solve this I can not find the formula?

Speed of light = frequency (1/s) * wavelength (m)
Therefore frequency= speed of light/wavelength
Frequency = 3 x 10^8/ 253 x 10^-9 = 1.18577 x 10^15 Hz.

Formula frequency = speed of light/wavelength
speed of light c= 310^8m/s wavelength = 25310^-9m
so frequency= 310^8/25310^-9 =1.18610^15 Herts or 1/s

wavelength = c/frequency
c is the speed of light, 3 x 10^8 m/s
frequency = c/wavelength
nanometros = 10^-9m
f=3x10^8/(253x10^-9) = 1,185,770,750,988,142
Or 1.185 x 10^15 Hz
Gigahertz is 10^9 Hz
Terahertz is 10^12 Hz
So this is 1,185 Terahertz. or THz.
