reflection (terms and curved mirrors)

Question 1

state the law of reflection

Answer 1

angle of incidence is equal to the angle of reflection

Question 2

what is the normal line

Answer 2

perpendicular to the reflective surface

Question 3

what is the incident ray

Answer 3

the light moving towards a reflective surface (first angle hitting reflective surface)

Question 4

what is the reflected ray

Answer 4

light bouncing off a reflective surface (reflected light ray)

Question 5

the characteristics of a plane mirror image are always

Answer 5

S - same size
A - upright
L - behind mirror
T - virtual
*laterally inverted

Question 6

state ray rule 1

Answer 6

rr1
- parallel to PA
- reflect back through F

Question 7

what is the principle axis

Answer 7

line drawn through the middle of mirror

Question 8

state ray rule 2

Answer 8

rr2
- through F
- reflected back parallel to PA

Question 9

what is the focal point

Answer 9

the point where light rays that are parallel to the PA either come together or diverge

Question 10

convex mirror makes rays

Answer 10

diverge (apart)

Question 11

concave mirror makes rays

Answer 11

converge (come together)

(

Answer 13

convex (facing outwards)
