>> The speed, wavelength, and frequency of a gravitational wave are related by the equation c = λf, just like the equation for a light wave [...] > To get a short wavelength requires a high frequency For light that is assuming a vacuum. The more general equation is c' = λf where c' is the speed of light in the medium the light is traveling through. c' <= c. Hence, for light, you can get a shorter wavelength without having to raise the frequency if you work with the light in a medium with a lower c'. Is there anything similar with gravitational waves?
