Question:medium
If the instantaneous displacement of a wave is $y = 2(\sin 2\pi t + \sqrt{3}\cos 2\pi t)\,cm$, then the amplitude of the wave in $cm$ is
If the instantaneous displacement of a wave is $y = 2(\sin 2\pi t + \sqrt{3}\cos 2\pi t)\,cm$, then the amplitude of the wave in $cm$ is
Show Hint
Amplitude of $a\sin\theta + b\cos\theta$ is $\sqrt{a^2 + b^2}$.
