What three interactions can occur when waves meet the boundary between two materials?
What three interactions can occur when waves meet the boundary between two materials?
Reflection, absorption, transmission
What is the relationship between angle of incidence and angle of reflection?
What is the relationship between angle of incidence and angle of reflection?
They are equal
How does surface smoothness affect the strength of reflected waves?
How does surface smoothness affect the strength of reflected waves?
Smoother surfaces create stronger reflection
Why do rough surfaces appear matt and not reflective?
Why do rough surfaces appear matt and not reflective?
They scatter light in all directions
What is transmission?
What is transmission?
Waves passing through a material
How does transparency affect light transmission through a material?
How does transparency affect light transmission through a material?
More transparent allows more light through
When does absorption of light occur?
When does absorption of light occur?
When light frequency matches electron energy
What happens to light energy after it is absorbed by electrons?
What happens to light energy after it is absorbed by electrons?
Reemitted over time as heat
If a material appears green, which frequencies of visible light have been absorbed?
If a material appears green, which frequencies of visible light have been absorbed?
All frequencies except green
What role do electrons play in reflection?
What role do electrons play in reflection?
Absorb light energy then reemit it
When will light reflect from a material?
When will light reflect from a material?
If object is opaque and light not absorbed
Can refraction occur during transmission?
Can refraction occur during transmission?
Yes, light can refract and still transmit
