Refraction occurs when light passes a boundary between two different transparent media e.g passes through air to water
Due to this speed and wavelength changes
This leads to a change in direction which is refraction
What do ray diagrams for refraction look like?
-3 Main Pieces
Consist of The normal
Angle of incidence
Angle of refraction
A)
When the wave hits the boundary of a different medium different parts hit the boundary at different times
A)
In a denser medium the wavelength decreases which can be seen on a diagram . Distance between each wavefront is less which showcases how the wavelength decreases
What is refraction like between Air and glass?
Bends away from the normal when entering the airAs the light enters the glass it bends towards the normal (The imaginary straight line going through the diagram) When re entering the air it bends away from the median again -Light slows down in denser materials. Glass is denser than air
A)
Acronym
Faster
Away
Slower
Towards
Answer the question?
It goes into a denser median. The acronym fast tells us that as it goes towards the normal it is slower which matches that a denser median is slower. As it exits it goes away from the median
A)
So what is a boundary in wave diagrams?
Represents the difference in wavelength between bounds so the less gap between bounds the higher the wavelength
