Wave- a travelling disturbance that carries energy from one location to another Wave Properties 2-D wave forms: Circular: Straight or Plane wave:
Wave Phenomena: equal to Reflection: Key principle: The angle of incidence is ___________ the angle of reflection. Normal Partial Reflection-Partial Refraction: When a wave strikes a boundary between two media, some of the energy will be reflected and some will be refracted.
Wave equation: v= f λ • Transmission between media: • Frequency remains constant when a wave travels into a second medium • If the wave speed is different, then the wavelength will change • V↑, λ↑- faster medium-wavelength increases • v↓, λ↓-slower medium, wavelength decreases Refraction: Occurs when a wave travels from one medium into a second medium at an oblique angle of incidence. The direction of the wave changes (the wave bends). The angle of refraction can be determined using Snell’s Law!
Diffraction: The spreading out of waves as they pass through a small opening or past a sharp barrier.
