1
Q
Snell’s Law
A
n1 sin(Θ1) = n2 sin(Θ2)
2
Q
Density and Refractive indices
A
Density increases as refractive index goes up
As a result Θ decreases for that medium
n=c/v, so higher density, lower velocity
3
Q
Critical angle
A
Θc, when refracted light is 90 degrees, light comes back at same angle, reflected
4
Q
Magnification equation
A
M = hi/h0 = -di/d0, image is inverted
5
Q
Pinhole camera
A
Image is smaller, real and inverted
6
Q
Convex Lens/concave mirror outside f
A
Real and inverted
lens: far side
mirror: close side
7
Q
Convex lens/concave mirror inside f
A
Virtual and upright
lens: close side
mirror: far side
8
Q
Concave lens/convex mirror
A
Virtual and upright
lens: close side
mirror: far side
9
Q
Property of real images
A
Real images are inverted
