Show answerHide answer
Answer: A
A gravitational wave is a stretching and squeezing ripple of space-time.
Question 2
Gravitational waves are produced by:
- AGentle breezes
- BViolent cosmic events such as colliding black holes or neutron stars
- CEarthquakes only
- DSolar wind
Show answerHide answer
Answer: B
Violent cosmic events like colliding black holes or neutron stars produce them.
Question 3

- ASound
- BAn aeroplane
- CLight
- DA satellite
Show answerHide answer
Answer: C
They travel through space-time at the speed of light.
Question 4
Gravitational waves carry information about their:
- ASource and the cosmic event that produced them
- BColour only
- CTemperature of Earth
- DLocal weather
Show answerHide answer
Answer: A
They carry information about the event that created them.
Question 5
A gravitational wave passing through a body causes a change in the:

- CCharge of the body
- DMelting point of the body
Show answerHide answer
Answer: B
They stretch and compress space so the length between objects changes.
