<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Requisite conditions for the occurrence of the phenomena of Gravitational Lensing include:

1. Huge amount of matter creating a distorting gravitational field
2. Light from distant galaxies
3. These distant galaxies should be out of line of sight.
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;}--> A gravitational lens can occur when a huge amount of matter, like a cluster of galaxies, creates a gravitational field that distorts and magnifies the light from distant galaxies that are behind it but in the same line of sight. The effect is like looking through a giant magnifying glass.
