Two plane monochromatic waves propagating in the same direction with amplitudes 3 A and 5 A and differing in phase by $\frac{2π}{3}$, superimpose. The amplitude of the resulting wave will be: |
$4 A$ $\sqrt{34}A$ $\sqrt{19}A$ $\sqrt{21}A$ |
$\sqrt{19}A$ |
The correct answer is Option (3) → $\sqrt{19}A$ |
