frequency's unit is Hz which mean cycles per second

given frequency * wavelength = speed of wave

speed of light = 3x10^8 m/s

wavelength = 680nm = 680x10^-9 m

frequency * 680x10^-9 m = 3x10^8 m/s

frequency = 3x10^8 / 680x10^-9

= 4.41x10^14 Hz

= 441x10^12 Hz

= 441 THz

which is the frequency for red light
