Skills to be mastered:

• Be able to use complex wave amplitudes;

• Understand the relation between wave intensity and its complex amplitude;

• Understand the superposition principle for complex wave amplitudes;

• Understand the derivation of the interference pattern from two or more narrow slits;

• Be able to determine the properties of a slit system that produces a known interference pattern;

• Be able to use phasors to illustrate interference.
