Which of the following statements correctly describes what is meant by diverging light rays? Is it (A) light rays are diverging if they get closer together as time passes and meet at a point? Is it option (B) light rays are diverging if they are parallel? Or is it (C) light rays are diverging if they get further apart as time passes?

This question is asking us about diverging rays of light. Remember that diverging means light rays are moving away from each other or spreading apart. Diverging rays of light can be produced by passing parallel rays of light through a concave lens.

So, to work out the answer to this question, we can draw the different options that have been described to us.

Option (A) says that the rays get closer and closer with the passage of time and meet at a point. We can see that these rays are not spreading out. In fact, these are converging rays, not diverging. So this is not the correct answer.

Option (B) tells us that the light rays are traveling parallel. If light rays are parallel, the distance between them is always the same. So, they’ll never intersect at any point or move away from each other either. This is also not a description of diverging light rays.

Finally, option (C) tells us that the rays get further apart with time, which is the definition of diverging light rays. So this is the correct answer.
