Math and English probably I don't quite understand ur question but I hope this helped
I’m not sure what this question exactly means but it could be anything ig
The equation that uses both wavelength and frequency is c = fλ. c is the speed of light, which is constant. So that means if f increases, then λ must decrease, and vice-versa. Since f and λ are going in different directions then that means that they are inversely proportional.
