Refraction Flashcards
1
Q
What is the refractive index of a material
A
The refractive index of a material is a measure of how easy it is for light to travel through it
2
Q
What is the formula for the refractive index of a material
A
n=c/cs
Where s is the material
3
Q
What does the higher the refractive index show?
A
The slower light can travel through it
The higher refractive index the denser the material
4
Q
What happens to light when it enters a denser material?
A
The denser material has a higher refractive index so the light bends towards the normal
5
Q
What is relative refractive index?
A
One of the two materials touch the boundary between them will have a refractive index dependent on the refractive indices of the two materials
6
Q
What is the equation for relative refractive index?
A
n=sinø1/sinø2
