Use the diagram to answer the question.

Which of the following best describes what is being shown in the diagram?

• The light source emits light rays. Light rays are reflected off the flower and enters the eyes through the pupil. We are then able to see the flower.

• The light source emits light rays. Light rays are blocked by the flower and do not enter the eyes. We are then able to see the flower.

• The light source emits light rays. Light rays enter our eyes through the pupil. We are then able to see the flower.

• Our eyes emit light rays. The light rays are reflected off the flower and enter the light source. We are then able to see the flower.

You go outside to play with your dog. It is a sunny day. You can easily see everything around you: your dog, trees, a swing set, grass, and a picnic table. How are you able to see all of these objects at once? Select the TWO correct answers.

• Light rays from many different directions reflect into your eyes.

• Alien rays from space reflect into your brain.

How are we able to still see objects that are in shadows?

• Light rays curve around the obstacle blocking the light and then hit the object is in the shadow.

• Light rays pass through the obstacle blocking the light and then hit the object through direct illumination.

• Light rays reflect off the obstacle, then reflect off several other objects before hitting the object in the shadow. This is indirect illumination.

• Light rays are emitted from our eyes to the object in the shadow. We are then able to see the object through indirect illumination.
