Waves And Sound Question 6
Question 6 - 29 January - Shift 1
Two simple harmonic waves having equal amplitudes of $8 cm$ and equal frequency of $10 Hz$ are moving along the same direction. The resultant amplitude is also $8 cm$. The phase difference between the individual waves is degree.
Show Answer
Answer: (120)
Solution:
Formula: Phase difference
$2 A \cos (\frac{\Delta \phi}{2})=A$
$\cos (\frac{\Delta \phi}{2})=\frac{1}{2}$
$\frac{\Delta \phi}{2}=60^{\circ}$
