Waves: Sound and Light IPC Unit 6
Waves ©Wave-a disturbance that transmits energy through space ©Most waves require a medium (matter through which a wave travels like water or air)
Two Types of Waves ©Transverse wave-particles of the medium vibrate perpendicular to the direction the wave ©Ex: wave in water, light wave
Transverse Waves © Crest-High point of a wave © Trough-Low point of a wave © Amplitude-Distance from rest position to crest or trough; amount of energy in wave © Wavelength (λ)-distance between any two successive identical parts of a wave © Crest crest, trough, rarefaction
Two Types of Waves ©Longitudinal wave-particles of the medium vibrate parallel to the direction of the wave ©Ex: slinky, sound wave
Longitudinal Waves © Compression–part of wave where the coils/particles are pressed together © Rarefaction–part of wave where the coils/particles are spread apart
Wave Interactions © Reflection-the bouncing back of a wave as it meets a surface or boundary
Wave Interactions © Refraction-the bending of waves as they pass from one medium to another
Wave Interactions © Diffraction-the bending of a wave as it passes an edge or an opening
Wave Interactions © Resonance-one vibration causes another vibration
Wave Interactions ©Interference-combination of two or more waves ©Constructive interference: waves combine so that the resulting wave is bigger than the original waves ©Destructive interference: waves combine so that the resulting wave is smaller than the original waves
