When two massive objects (like black holes) orbit each other, they emit gravitational waves as sometimes their axis is oriented one way and sometimes transversely, creating alternating regions of strong and weak curvature, similar (but not identical) to periodically shaking one end of a string (see gif). If the binary systemrotates one full cycle every 6 days, what is the speed, frequency, and wavelength ofthe emitted gravitational waves
