The $SI$ unit of intensity of wave is

If $\upsilon_{s}$ is the velocity of sound in air and $\upsilon$ is the $rms$ value, then

A wave is expressed by the equation $ y= a\,sin [\frac{\pi x}{2a} - \frac{\pi t}{2}]$ where $x$ and $y$ are in $m$ and $t$ in $s$. The distance travelled by the wave in $3 \,s$ is

A cylindrical tube, open at both ends, has a fundamental frequency $f$ in air. The tube is dipped vertically in water so that half of it is in water. The fundamental frequency of the air column is

The relation between phase difference and path difference is

The equation $y = 4cos(2\pi x)cos(2\pi t)$ represents
