The student wants to present LIGO's aim and methodology. Which choice most effectively uses relevant information from the notes to accomplish this goal? While researching a topic, a student has taken the following notes: * Gravitational waves are powerful ripples that originate in deep space and eventually pass through Earth. * The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a physics study that began in 2002. * LIGO's goal is to detect and analyze gravitational waves. * LIGO uses a pair of massive gravitational wave detectors called interferometers that are thousands of miles apart. * In 2015, for the first time in history, LIGO researchers detected a gravitational wave passing through Earth.
- 1In 2015, LIGO's massive interferometers detected a powerful ripple that originated in deep space and eventually passed through Earth.
- 2Though the physics study LIGO began in 2002, its massive interferometers didn't detect a gravitational wave until2015.
- 3To achieve its aims, LIGO uses a pair of massive interferometers that are thousands of mi les apart.
- 4A physics study designed to detect and analyze gravitational waves, LIGO uses a pair of massiv e interferometers that are thousands of miles apart.✓
Correct answer
A physics study designed to detect and analyze gravitational waves, LIGO uses a pair of massiv e interferometers that are thousands of miles apart.
