Reflection Flashcards
Draw a diagram of wave reflection
Look in the book (gcse physics)
How do ALL waves travel to different material
Absorbed , transmitted or reflected
Meaning of absorbed
Wave is absorbed into the material , transferring energy to it
Meaning of transmitted
Wave Carries on travelling through the material
Meaning of reflected
The wave bounces off the material
What effects weather a wave is absorbed transmitted or reflected
The wavelength and the properties of the material
Name two types of reflection
Specular or difffuse
What is specular reflection
It happens when a wave is reflected in a single direction by a smooth surface eg light reflected by a minor (see diagram)
What is diffuse reflection
It is when a wave is reflected by a rough surface eg a piece of paper
