Answer 1

Answer:

Light (or any other wave) is characterized by its wavelength or its frequency. ... Since frequency is the number of waves that pass by a point per second, and the wavelength is the distance between consecutive peaks of that wave, you can determine the speed of the wave by multiplying these two numbers, that is: c=λν.
