Light Flashcards
1
Q
Refraction
A
The bending of light as it goes from one medium to another
2
Q
Laws of Refraction
A
1) Incident ray, refracted ray and normal are on the same plane 2) Sine I/Sine R is constant
3
Q
Refractive Index
A
Sine I/Sine R = 1/Sin C = Real Depth/Apparent Depth = c1/c2
4
Q
Critical Angle
A
The angle whose angle of incidence is 90 when light goes from a denser to a rarer medium
5
Q
Total Internal Reflection
A
When light travelling from a denser to a rarer medium strikes the second medium with an angle of incidence greater than the critical angle, it is reflected back
