1D: refraction and reflection

Angle of incidence

The angle to the normal of a ray approaching a medium boundary

angle of reflection

the angle to the normal of a ray reflected at a medium boundary

Angle of incidence

The angle to the normal of a ray approaching a medium boundary

angle of reflection

the angle to the normal of a ray reflected at a medium boundary

angle of refraction

the angle to the normal of a ray refracted at a medium boundary

critical boundary

the angle above which total internal reflection occurs

normal

an imaginary line perpendicular to the medium boundary at the point of incidence

refraction

the change in direction of a wave moving between two mediums with different refractive indices

refractive index

for a given medium, the ration of the speed of light in a vacuum to the speed of light in that medium

total internal reflection

the reflection of all incident light at a boundary between two mediums

transmission

the transfer of wave energy through or between wave mediums

refractive index formula

n= c/v (n- refractive index of medium, c- speed of light in a vacuum, v- speed of light in medium)

refractive index and wave speed formula

n1v1=n2v2

Snell’s law

n1sin(θ1)=n2sin(θ2)

critical angle

n1sin(θc)=n2

wave equation (frequency)

v=fλ
