Physics Waves & Oscillations questions from NEET UG 2012.
The equation of a simple harmonic wave is given by $$ y=3 \sin \frac{\pi}{2}(50 t-x) $$ where $x$ and $y$ are in metres and $t$ is in seconds. The ratio of maximum particle velocity to the wave velocity is
Two sources of sound placed close to each other, are emitting progressive waves given by $y_1=4 \sin 600 \pi t \text { and } y_2=5 \sin 608 \pi t$ An observer located near these two sources of sound will hear
When a string is divided into three segments of lengths $l_1, l_2$ and $l_3$, the fundamental frequencies of these three segments are $v_1$, $v_2$ and $v_3$ respectively. The original fundamental frequency $(v)$ of the string is
