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

Real Image Virtual Image

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
