*12.2.3.a Students will describe mechanical wave properties (speed, wavelength, frequency) and how waves travel through a medium
*12.2.3.b Students will recognize that the energy in waves can be changed into other forms of energy
*12.2.3.c Students will recognize that light can behave as a wave (diffraction and interference)
*12.2.3.f Students will recognize that the production of electromagnetic waves is a result of changes in the motion of charges or by a changing magnetic field.
