What are the three uses for the ray model?
1. Help in understanding what happens when light energy reaches different materials. 2.You can predict where shadows will form and how large they will be. 3. Can show the difference between a transparent material and a translucent material.
How is an opaque material different from a translucent material?
An opaque material prevents any light from passing through it while translucent materials lets most light rays through, but are scattered in all directions.
How is translucent material different from a transparent material?
Translucent material scatters the light rays in different directions while transparent material transmits the rays orderly and they can be seen through the material
Is a glass of water with red food colouring in it translucent or transparent? Explain.
It is transparent because you can clearly see through the water even though it has colour added to it.
What is the relationship between the size of the shadow and the distance of the object from the light source?
The more farther away the object is from the light source the more smaller the shadow would be.
