question 17

Multiple Choice

Write the equation of a wave, travelling along the +x axis with an amplitude of 0.02 m, a frequency of 440 Hz, and a speed of 330 m/sec.

• A)y = 0.02 sin [880 \(\pi\)(x/330 -t)]
• B)y = 0.02 cos [880 \(\pi\) x/330 -440t]
• C)y = 0.02 sin [880 \(\pi\)(x/330 + t)]
• D)y = 0.02 sin [2 \(\pi\)(x/330 + 440t)]
• E)y = 0.02 cos [2 \(\pi\)0(x/330 + 440t)]
