Chapter 1 Waves

Study for the test.

Wave A traveling disturbance that carries energy from one place to another
Mechanical waves are created when a source of energy causes a medium to move
Speed = wavelength multiplied by frequency
Refraction The bending of waves due to a change in speed
Diffraction The bending of waves around an obstacle
Interference The interaction between two waves that meet
Constructive Interference When waves combine to make a wave with larger amplitude
Standing wave When an incoming wave combines with a reflected wave in such a way that the combined wave appear to be standing still
Resonant Frequency When vibration travels through an object at the same speed of the object it travels through
the energy passes from one particle to another A wave travels through a medium because
How they move A mechanical wave is classified according to
Hertz Frequency is measured in
Reflection When a wave hits a surface and bounces off of that surface
Destructive Interference When waves combine to produce a smaller or zero- amplitude wave
Light travels faster then sound The reason for why you see lightning before hearing thunder
Longitudinal Wave Compression and rarefaction are characteristics of a
Wavelength The distance between two consecutive crests
Transverse Wave Where the motion of the medium of the wave is traveling at a right angle to the motion of the wave
Frequency Waves / Seconds
Compression Space where the particles are crowded together
Rarefaction Space between compression
