1

What is the relationship between Rays and Wavefronts?

They are perpendicular from one another

2

How are wavefronts and rays from a real object?

Diverging

3

Wavefronts flatten as the

Distance from the object incrases

4

What happens when Wavefronts flatten?

They become parallel light / collimated light / plane waves

5

Rays leaving the lens / system point to

An image point

6

What happens to curvature in diverging wavefronts?

They lose curvature as they travel

7

What happens to curvature in converging wavefronts?

They gain curvature as they travel

8

What is the equation of Curvature?

1 / radius of the sphere

9

For light traveling in air, vergence is equal to

Curvature

10

What are the units of Curvature?

Diapters (D), which is m-1

11

Lens power is a measure of

How much the lens changes the curvature of wavefronts incident upon it

12

How is curvature and vergence when light is diverging?

Negative

13

How is curvature and vergence when light is converging?

Positive

14

Light travels in what direction?

Left to right
