Question

Gravitational waves from a pair of coalescing neutron stars

Pick those that apply

1. were observed with Michelson interfereometers

2. affect the two arms of a Michelson interferometer differently

3. alter the speed of light

4. change the 4 km path of light by a distance less than the diameter of a proton

5. show that light and gravity travel at the same speed

Yes gravitational waves are obsered using Michelson interferometer.

Yes, they affect two arms differently,which produces the phase difference and is thus detected.

No, they travel at c themselves.

Yes, the statement is true

Yes, they both travel at speed of causality i.e of light (c).
