Focal length =

A
7
Q

Plane mirrors:

A

Virtual, upright

SAME size

behind mirror

8
Q

What is the length of a mirror needed to see an entire object?

A

1/2 of object height

9
Q

Convex

A
10
Q

Concave

A
11
Q

The more curved the mirror is

A

the more blurry the image

12
Q

The smaller the size of the mirror compared to the radius of curvature (r)

A

the more focused the image (rays will cross at a single point –> focus)

13
Q

What kind of mirrors will reflect rays to a perfect focus?

A

parabolic mirrors

14
Q

What are 4 rays to draw when doing mirror ray diagrams?

CONCAVE MIRROR

A
1. Enter parallel → exit through F
2. Enter through F → exit parallel
3. Enter through C (perpendicular to mirror) → exit back on itself
4. Enter incident at the optical axis → reflected back same angle

Q

Images from CONVEX mirrors are always?

A

virtual, upright, behind mirror

F = negative

1/do: +

1/di: –

22
Q

4 Rays to draw for ray diagram CONVEX mirror

A
1. Enters parallel → appears to exit coming from F
2. Enters aimed at C → reflected back on itself
3. Enters aimed at F → exits parallel
4. Enters incident to optical axis → reflected back same angle
