Gravitational waves are also redshifted?

Click For Summary
SUMMARY

Gravitational waves emitted from a source with frequency f experience redshift when approaching a black hole, similar to the behavior of ordinary light. Both the frequency and energy of gravitational waves decrease as they approach the event horizon. Furthermore, gravitational waves cannot escape from within the event horizon of a black hole, confirming their inability to transmit information from that region.

PREREQUISITES
  • Understanding of gravitational wave physics
  • Familiarity with black hole event horizons
  • Knowledge of redshift phenomena in astrophysics
  • Basic principles of general relativity
NEXT STEPS
  • Research the properties of gravitational waves using LIGO data analysis
  • Explore the implications of redshift in the context of black hole thermodynamics
  • Study the mathematical framework of general relativity related to black holes
  • Investigate the differences between gravitational waves and electromagnetic waves
USEFUL FOR

Astronomers, physicists, and students of astrophysics interested in the behavior of gravitational waves in strong gravitational fields.

I want to confirm one thing.

Say, I have an emitter of gravitational waves with frequency f.
I throw it into black hole.
Is it correct to assume that:

1. frequency f and energy of GR waves are decreased in exactly the same manner as frequency and energy of ordinary light?
2. and GR waves can't escape from regions inside the horizon?

Thanks.
