A star 10 light-years away explodes and produces gravitational waves. How long will it take these waves to reach Earth?
Solution 16RQ Introduction The gravitational waves are ripples in the curvature of space-time. It will propagate with the velocity of light. If a star is exploded, the gravitational waves will be produced. The gravitational waves are similar to electromagnetic radiation. Step 1 In this problem, provided, a star 10 light years far from earth is exploded produces gravitational waves. Since the gravitational waves travel with the speed of light “c”, it will take the exact time for the light to travel the distance to reach the earth. So, if the star is 10 light years far from earth, the gravitational waves will take the exact 10 light years to reach the earth. Conclusion Gravitational waves and light have the same velocity.
