Wave Interference<br />
<strong><strong>wave</strong>s</strong> approach…<br />
<strong>wave</strong> interference<br />
begins…<br />
constructive interference: crests<br />
and troughs <strong>of</strong> <strong><strong>wave</strong>s</strong> coincide<br />
maximum <strong>wave</strong><br />
interference…<br />
<strong>wave</strong> interference<br />
ends…<br />
<strong><strong>wave</strong>s</strong> recede as<br />
though nothing<br />
happened.<br />
destructive interference: crests <strong>of</strong><br />
one <strong>wave</strong> coincides with troughs<br />
<strong>of</strong> the other<br />
complete destructive interference:<br />
amplitudes <strong>of</strong> <strong><strong>wave</strong>s</strong> are also the<br />
same.<br />
