So there is some kind of reciprocal relationship whereby one has never discovered a long wave with a high frequency or vise versa? Just asking.
It depends on if you're talking about a waves in the water or light. It goes back to the speed of a wave being defined as the wavelength in distance multiplied by the frequency in Hertz. If you have a long wave with a high frequency, the speed is going to be faster than a short wave with a low frequency. A short wave with a low frequency would be an occasional ripple on still water, where a long wave with a high frequency would be rough seas. Now all light is pegged at the speed of light, so yes, there's a reciprocal relationship between frequency and wavelength for light energy. We make use of this principle when calculating the speed of light from the frequency of a microwave oven and the distance between the hot spots.
