OBJ: Given activity sheet, notes, video SWBAT explain the types of images produced by a plane, concave and convex mirror with 70% accuracy. DN: Hand-in Light, Prism, Filter (college style) Lab [including conclusion questions, Abstract Form] Distribute: Sound & Light Review Sheets Video: Mirrors & Lenses ACT: Introduction to: Diffuse vs Regular Reflection Virtual vs Real images Planar, Concave, Convex Mirrors Text, Read p. 113-118, Work on Reflection and Mirrors Booklet HW: Complete Reflection and Mirrors Booklet; Work on Sound & Light Review Sheets, Light Exam, Monday Dec 8; SVQ2 Quiz (erosion-magnetic force, week of Dec 8)
2
Upcoming Sound & Light Exam Cause of sound (vibration) How sound moves Ear Parts/Function bell jar/vacuum experiment
3
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]
4
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.
6
Virtual vs Real Images Image: copy of an object formed by reflected or refracted light Virtual Image: image upright, erect Real Image: upside down
7
Real Image Virtual Image
8
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
9

10
