Questions & Answers

Q: Why can't we see rays of light during the day?

We cannot see rays of light during the day because there is an abundance of sunlight that makes it difficult to distinguish individual rays.

Q: How can we visualize rays of light?

Rays of light can be visualized by going into a dark room, closing all doors and windows, and leaving a tiny hole open. The sunlight entering through the hole will show the rays of light.

Q: What is the difference between a line and a ray?

A line extends indefinitely in both directions, while a ray extends indefinitely in one direction and has one fixed end.

Q: How do we represent a ray of light?

A ray of light is represented by a line with an arrow sign above it. The arrow indicates the direction in which the ray extends indefinitely.

Summary & Key Takeaways

• Rays of light are not visible during the day because there is too much sunlight everywhere, but they can be seen in a dark room with a tiny hole.

• A ray is an intermediate between a line and a line segment, with one fixed end and one end extending indefinitely.

• Rays of light can be represented by a line with an arrow sign above, with the arrow indicating the direction of the ray.
