1

The increase in the index of refraction results in the

Decrease in light velocity

2

What happens when light travels?

The wavelength changes but the frequency does not

3

What is the equation to find wavelength?

w = c / f

4

What is the equation for speed of light not in vacuum?

v = c / n

5

What is the equation to find wavelength in a medium?

wavelength medium = wavelength / n

6

Light travels slower in

Water compared to air

7

For light rays going into the water, how do they bend?

Towards the normal

8

What happens if n2>n1?

The ray bends towards the normal, making i > r

9

What happens if n2

The ray bends away from the normal, making i < r

10

What happens to curvature in diverging wavefronts?

They lose it

11

What happens to curvature in converging wavefronts?

They gain it

12

What is the equation for Vergence?

V = n / v (small)

13

What is the equation for Vergence?

V = n • curvature

14

What are the equations for focal points?

P = 1 / f2 or 1 / -f1

15

What is the equation for Magnification?

M = I/O or U/V

16

What is the equation for Total Magnification?

mT = M1•M2

17

An object at infinity produces an

Image at F2

18

An object at F1 produces an

Image at infinity

19

An object to the left of F1 in converging lenses forms an

Image at the right of F2

20

In a Diverging Lens, diverging wavefronts produce

An image between F2 and the lens

21

In a Diverging Lens, converging wavefronts produce

An image either left of F2 or right of the lens

22

In a Diverging Lens, an object between both the Lens and F1 produces a

Real Image

23

In a Diverging Lens, an object to the right of F1 produces a

Virtual image

33

In Diverging Lenses, where is the image found if an object is between F1 and the lens?

- Between lens and F1
- At F1
- To the right of F1

34

In Diverging Lenses, if an image is located at F1, it means that the object is

In Diverging Lenses, if an image is located between F2 and the lens, it means that the object is

- Real
- To the left of F2
- At F2
- Between F2 and the lens
