|
What are three things light can do |
Reflect Refract Be absorbed |
|
|
How is the angle of incidence related to the angle of reflection? |
The angle of incidence is the incoming of light and is equal to the angle of reflection going out |
|
|
What is the difference between reflection and refraction? Which one uses lenses and which one uses mirrors? |
Reflection- bouncing of light by mirrors Refraction- bending of light through lenses |
|
|
What happens when light enters a prism |
The light refracts and spreads out to show the colors of the visible spectrum |
|
|
What causes light to refract |
It changes speed as it enters a new medium or material |
|
|
What is diffraction |
Diffraction is when light bends around something |
