Question

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Phenomena of Gravitational lensing could led to :

1. Multiple images of distant galaxy or star acting as light source
2. Formation of Einstein's ring
3. Distortion in magnetic field of Earth
Which of the following statements is/are correct?

• A. 1 and 2 only
• B. 2 and 3 only
• C. 1 and 3 only
• D. 1, 2 and 3

Answer 1

The correct option is A 1 and 2 only

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Gravitational lensing leads to bending of light leading to formation of multiple images of distant galaxies or star ,which are the source of that light. And when gravitational lensing approaches the perfect symmetry, a complete or almost-complete circle of light is produced, called an Einstein ring.Earth's magnetic field is not impacted by gravitational lensing.
