Physics 6.2.4 Flashcards
When does Refraction Occur?
Refraction Occurs when Light Passes a Boundary Between 2 Different Transparent Media.
What happens at the Boundary Between 2 Different Transparent Media in Refraction?
The Light Rays Undergo a Change in Direction.
Why do Light Rays Change Direction in Refraction?
The Wave Speed is Different in Different Mediums. When Wave Speed Changes, the Wavelength must also Change to accommodate. Therefore, the Direction Changes.
The Direction of Refracted Light is Taken as the Angle from a Hypothetical Line Called the…
Normal.
What is the ‘Normal’?
The Normal is the Hypothetical Line where the Direction of Refracted Light is Taken from as an Angle.
From Less Dense Medium to More Dense Medium, Light Bends ___ the Normal.
Towards.
From More Dense Medium to Less Dense Medium, Light Bends ___ from the Normal.
Away.
When Passing along the Normal, how does the Light Bend?
The Light does not Bend at all.
