Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on thewavelength. ... The equation that relates wavelengthand frequency for electromagnetic waves is: λν=c where λ is the wavelength, ν is the frequency and c is the speed of light.

time- period=1/frequency
frequency=1/time-period
both are reciprocal of each other
frequency=1/time-period
