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
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.
