2. Reflection

   • Sound waves and light waves reflect from surfaces.
   • The angle of incidence equals the angle of reflection

3. Waves

   • Longitudinal Waves
     • Oscillations are along the same direction as the energy travel
     • P waves are the same as longitudinal waves
   • Transverse Waves
     • the oscillations are at right angles to the direction of travel and energy transfer.
     • Water waves and S waves are also transverse waves.

4. Refraction

   • Key Words: -Densities -Angle of incidence -Reflected -White light -Prism-Wavelengths
   • Sound waves and light waves change speed when two surfaces have different ( Glass and Air)
     • Makes the wave change diecton
   • If you increase the angle of incidence the greater the angle of refraction.

5. Sound

   • The number of waves per second is measured in Hertz (Hz)
