9 Quiz Test your knowledge of gravitational waves and detectors with this short quiz 1 / 8 Which of these interferometers is not completed yet? LIGO Hanford Virgo KAGRA LIGO India LIGO India is still in the planning stage! 2 / 8 Which of these is not used in the analysis of gravitational wave data? Bandpassing Whitening Upsamping Matched filtering Downsampling is used 3 / 8 Which of these gravitational waves was detected first? GW151226 GW170817 GW150914 GW190814 GW150419 was the first wave detected by LIGO 4 / 8 Which of these is NOT a gravitational wave source LIGO currently detects? Binary black hole merger Supernova Neutron star merger Neutron star collision Supernovae do generate gravitational waves but we cannot detect them yet 5 / 8 Gravitational waves are created by symmetrical explosions True False Gravitational waves are created by accelerating masses. This does include asymmetrical explosions, so one day we could detect a supernova (an exploding star)! 6 / 8 What is the name of the space-based Interferometer currently being developed by ESA and NASA? MARGE BART HOMER LISA It is LISA! It stands for the Laser Interferometer Space Antenna 7 / 8 What kind of graph is this? Q-transform K-transform J-transform L-transform This is a q-transform. They are very useful for visualising data 8 / 8 How many observing runs has LIGO completed? 2 3 4 5 LIGO AND VIRGO have completed three observing runs, with the fourth planned for March 2023 Your score isThe average score is 67% LinkedIn Facebook 0% Restart quiz Header: NASA on Unsplash
