Answers to page 452

• 42) Black does not reflect any light.• 43) Yellow-green (550 nm) is easiest to spot.• 44) Yellow light will show yellow paint better.• 45) Diminish by an inverse squared factor.• 46) Will not change, the lamp stays the same.• 49) Yellow, add colors of light.• 50) Black, subtract pigment colors.• 51) Mix just the cyan and magenta.

Mirrors

• I can draw reflected ray diagrams using angle of incidence = angle of reflection.

• I know the terms: principal axis, concave, convex, focal length, focal pt., geometric center, inverted, converge, diverge, real image, virtual image, spherical aberration and chromatic aberration.

• I know how rays of light reflect (ie, light parallel to the principle axis and light through the focal point)

• I can create a ray diagram.

• Given an object and a mirror I can fully describe the image

• Fully describe—real/virtual, relative size, relative location, upright/inverted

• I can calculate the image distance given focal length and distance from mirror.

• I can calculate heights and distances given magnifications

• I know mathematically how focal length and center of curvature are related.
