physics

• what are the two types of waves?

  transverse

  longitudinal
• what is the displacement to enegery transfer orientation for both waves?

  transverse - energy transfer perpendicular to displacement

  longitudinal - energy transfer is parallel to displacement
• what are the radian values for each part of a transverse wave?

  90 - π/2

  180 - π

  270 - 3π/2

  360 - 2π
• what is diffraction?


  the tendancy of a wave to spread out
• when might diffraction happen?


  when a wave passes through a gap
