Question

Diego drew a diagram to illustrate evidence that scientists use to support part of Einstein’s general theory of relativity. An illustration of the earth, a massive galaxy, a quasar and the image of quasar at two different positions. The actual quasar light goes from the quasar around the massive galaxy to the earth on both sides of the massive galaxy. The image light from the image however does not bend and is a straight path from the earth out to the image of the quasar on both sides of the massive galaxy. Which phenomenon does Diego’s diagram illustrate? gravitational redshift gravitational time dilation principle of equivalence gravitational lensing

Answer 1

gravitational lensing

Step-by-step explanation:

Answer 2

gravitational lensing

Step-by-step explanation:

One of Einstein´s general relativity predictions is that light follows the curvature of space-time, meaning that matter is capable of bending light traveling from a distant object to an observer when it´s between the source and the observer, this is called gravitational lensing. There are 3 types: strong, weak and microlensing. In the example, the fact that the light of the quasar goes around the galaxy, forming an arc, or a ring, and appears on both sides of the galaxy, suggesting that it´s an Einstein ring, which is an example of strong gravitational lensing.
