If two waves, each of intensity \( I_{0} \), having the same
\( \mathrm{P} \)
frequency but differing by a constant phase angle of \( 60^{\circ} \), superpose at a certain point in space, then the intensity of resultant wave is:
(1) \( 2 I_{0} \)
(2) \( \sqrt{3} I_{0} \)
(3) \( 3 I_{0} \)
(4) \( 4 I_{0} \)
(4) (D) (8) (अ) (a) ๑)
