Chapter 25 Part 2

Question 1

Flat Mirrors

Answer 1

The image formed by 
an object placed in 
front of a flat mirror is 
as far behind the 
mirror as the object is 
in front of the mirror; Lateral magnification

p=lql h=h’

M=h’/h

Question 2

Flat Mirrors

Answer 2

1. The image is as far behind the mirror as the object is
   in front.
2. The image is UNMAGNIFIED, VIRTUAL, and UPRIGHT.
3. The image has an apparent LEFT-RIGHT REVERSAL.

Question 3

Flat Mirrors

Answer 3

Daytime: Brighter reflection (mirror tilted in)

Nighttime: Darker reflection (mirror tilted out)

Question 4

Spherical Mirrors (Concave)

Answer 4

Produces real image

All SMALL reflected angles go to the same image point

Question 5

Spherical Aberration

Answer 5

Rays that make a LARGE angle with the principal axis diverge(rays intersecting at different points on principle axis), producing
a blurred image

Question 6

Spherical Mirrors (Concave)

Answer 6

Real image at two reflected rays intersect

M=h’/h=-q/p

Question 7

Mirror Equation

Answer 7

1/p+1/q=2/R=1/f

Question 8

Convex Mirror

Answer 8

The image formed by the object is virtual, upright, and behind the mirror

Equations for concave mirrors still apply, as long as we use the correct signs

Question 9

Note

Answer 9

C is is twice as large as F

C and F are behind convex mirrors

Question 10

Converging Lenses

Answer 10

Biconvex
Concave-Convex
Plano-Convex

Question 11

Diverging Lenses (Dive In Cave)

Answer 11

Biconcave
Concave-Convex
Plano-Concave

Question 12

Thin lenses

Answer 12

Converging: parallel->towards same F point

Diverging: parallel->away from F point
