I know that the formula to calculate the speed of light is c=fλ. F is the frequency, c is the speed, and λ is the wavelength. So how do I calculate the wavelength of a purple light with a frequency of 750 * 10^12 HZ. Frequency is measured in HZ. The speed is measured in m/second.

wavelength=speedlight/frequency
= 3E8/750E12 = 3/750 E4 meters
work it out
