Upcoming Sound &Light Exam
• Luminous vs. illuminated
• Transparent, translucent, opaque
• Light & Color (primary, secondary,
complementary), color triangle, pigments
• Reflection & Mirrors (image, virtual vs real
images, diffuse vs regular reflection; planar,
concave, convex mirrors)
• Refraction and Lenses (lens; convex vs.concave
lenses)
• Human eye (parts & functions); nearsightedness
vs. farsightedness and correction
• EM Spectrum [order (R,M,I,V,U,X,G), frequency,
wavelength, helpful vs harmful]
Diffuse vs Regular Reflection
• Reflection: light rays bounce off a surface
• Diffuse Reflection: rough surface; light
rays not parallel, scattered in different
directions, no image seen (blurry image)
• Regular (specular) Reflection: smooth
surface, parallel light rays; image seen.
Virtual vs Real Images
Image: copy of an object formed by
reflected or refracted light
Virtual Image: image upright, erect
Real Image: upside down

Mirrors; Read p. 113-118
• Planar Mirror: flat; image reversed and virtual
(upright )
• Concave Mirror: spoon, bowl-like, curve inward;
image virtual or real (upside down); enlarged or
reduced
• Convex Mirror: dome-shaped, curve outward;
image virtual (upright) & reduced (divergent
rays); car mirrors
• Divergent: spread apart
• Convergent: come together
