WAVE BEHAVIORS

REFLECTION

• THE BOUNCING BACK OF A RAY THAT WASNT SUPPOSE TO GO THROUGH
• Sound ex: echo
• Light ex: waves from sun are reflected when they strike the surface of the moon

LAW OF REFLECTION

REFRACTION

• The bending of a wave as it passes between two substances
• Light ex: flashlight beams as it flashes through the water
• When the wave enters a new medium, it changes wave length & speed. the wave bends and travels in a new direction

DIFFRACTION

• A change in the direction of a wave when the wave finds an obstacle or an edge
• Sound ex: music around a corner of a building
• Light ex: eclipse of the moon

INTERFERENCE

• The combination of two to more waves that results in a single wave
• Light ex: dark and light on a tv screen
• Sound ex: sonic boom

INTERFERENCE

• Constructive: when waves combine and the amplitude gets larger
• Destructive: when two waves with the same amplitude combine by destructive interference they cancel each other out

RESONANCE

• Makes two objects naturally vibrate at the same frequency
• Sound ex: marimba produces notes through the resonance of air columns
