Clicker question 4<br />
Two loud speakers emit <strong><strong>wave</strong>s</strong> with λ = <strong>2.</strong>0 m. Speaker 2 is<br />
<strong>1.</strong>0 m to the right <strong>of</strong> speaker <strong>1.</strong> What, if anything, must be<br />
done to speaker 1 to cause constructive interference between<br />
the two <strong><strong>wave</strong>s</strong>?<br />
a) move it <strong>1.</strong>0 m to the right<br />
b) move it 0.5 m to the right<br />
c) move it 0.5 m to the left<br />
d) move it <strong>1.</strong>0 m to the left<br />
Remember, you must consider<br />
both the shift and the phase<br />
e) nothing; there is already<br />
perfect constructive interference<br />
between the two <strong><strong>wave</strong>s</strong><br />
