Wave BehaviorsA. Reflection (Fig. 10-13, 10-14) (p. 301-302)–
bouncing back of a wave as it meets a boundary or surface
- Examples: Echoes, Looking in a mirror

Wave BehaviorsB. Refraction (Fig 10-15, 10-16, 10-17) (p 302-303)–
bending of waves as they pass from one medium to another

Wave BehaviorsC. Diffraction (Fig. 10-18, 10-19, 10-20)
(pages 304-305)– bending of waves around an edge

Wave Interactions
D. Interferance –
combination of 2 or more waves
usually produces one wave
(bigger if in phase)
(smaller if out of phase)

Wave InteractionsConstructive interference – when
waves combine to create a bigger wave
sum of the amplitudes of the waves
Example drawing – figure 10-21 (p 306)

Wave Interactions2. Destructive interference – when waves combine to form a smaller or no wave
some may completely cancel out difference between the amplitudes of the waves- Example drawing – figure 10-22 (page 307)

Wave Interactions E. Wave speed depends on
the mediumex. Sound moves fastest through
solids moves moderately fast
through liquids moves slowest through
air/gases (340 m/s)
- due to movement of molecules in the medium

Wave InteractionsF. Light travels at a constant speed
3x 108 m/s = 300,000,000 m/s (186,000 miles/sec.)
