Physics · Gravitational Waves & Astronomy
Consider the following statements regarding gravitational waves and interferometric observatories: I. Gravitational waves are distortions in space-time generated by massive accelerating bodies such as merging black holes or neutron stars. II. Laser interferometers used in gravitational wave observatories detect extremely small changes in the relative lengths of perpendicular arms. III. Gravitational waves travel faster than electromagnetic waves in vacuum because they are not affected by matter. IV. A global network of gravitational wave observatories improves the ability to localize the cosmic source of detected signals. Which of the statements given above are correct?
