Critical Angle And Refractive Index Flashcards
1
Q
What is the formula for critical angle
A
Sin C = 1/n
2
Q
What is the formula for refractive index
A
N = Sini/ sinr
N=c/v
3
Q
What is refractive index
A
How fast light travels in material
4
Q
What is refraction
A
When a wave slows or speeds up at a boundary between two materials
5
Q
What is the angle of incidence
A
The angle between the incoming wave and the normal
6
Q
What is the normal
A
An imaginary line that is perpendicular to the surface at the point of incidence
7
Q
What is critical angle
A
Is the angle of incidence where the angle of refraction in 90 degrees where light travels from more dense to less dense material
8
Q
What is the equation for critical angle
A
Sin C = 1/n
