QJEEM22Ph8fb3: JEE Main 2022 Physics - Class 11 JEEM22Ph8fb3 Solution: Two travelling waves of equal amplitudes and equal frequencies…

Two travelling waves of equal amplitudes and equal frequencies move in opposite directions along a string. They interfere to produce a stationary wave whose equation is given by $$y=(10\cos \pi x\sin \frac{2\pi t}{T})$$ cm

The amplitude of the particle at $$x=\frac{4}{3}$$ cm will be ___________ cm.
