  1. More wave definitions

  2. reflection • The bouncing back as a wave hits a surface • Free boundary – one end is free to move up and down, wave will be identical to the first wave • Fixed boundary – one end is fixed – wave will be opposite to the original wave

  3. Example or reflection

  4. refraction • Bending of waves when they pass from one medium to another less density to greater density

  5. interference Two waves in the same spot As they pass through each other, they create a new wave. After they pass each other they go back to their original size

  6. Constructive interference • Two wave passing and the crests line up creating a larger wave as they pass. After they pass they go back to original size

  7. Destructive wave interference When two waves pass each other and the crest and trough line up creating a smaller wave as they pass – after they go back to original size

  8. Standing wave • When two waves interfere that have the same amplitude and speed they look like they are not moving only revolving

  9. Doppler effect • A moving vibration pushes the wave in front making a higher frequency shorter wavelength higher pitch and the wave behind stretch out making a lower frequency – longer wave length lower pitch

  10. Doppler with light waves • The color of light for something going away would be red (wave stretched ou making longer wavelengths) – coming closer would be blue (waves pushed together making shorter wavelengths • Red shift Blue shift – that’s how we know the universe is expanding
