When two waves of exactly similar frequency (coming from two coherent sources) travels in a medium, in the similar direction simultaneously then because of their superposition, at some position intensity of light is maximum while at some other points intensity is minimum. This process is called as Interference of light.
What do you mean by the ratio of the frequency of fourth overtone to the fundamental frequency of a stretched string?
