It takes $2.0$ seconds for a sound wave to travel between two fixed points when the day temperature is ${10^o}C.$ If the temperature rise to ${30^o}C$ the sound wave travels between the same fixed parts in ...... $sec$
Two tuning forks have frequencies $450\, Hz$ and $454\, Hz$ respectively. On sounding these forks together, the time interval between successive maximum intensities will be .... $sec$
Figure given below shows four progressive waves $A, B, C$ and $D$ with their phases expressed with respect to the wave $A$ . It can be calculated from the figure that
The vibration of a string fixed at both ends are described by $Y= 2 \,\,sin(\pi x) \,\,sin\,\,(100\pi t)$ where $Y$ is in $mm$,$x$ is in $cm$,$t$ in $sec$ then
A standing wave in a pipe with a length $L=1.2 \,m$ is described by $y(x, t)=y_0 \sin [(2 \pi / L) x] \sin [(2 \pi / L) x+\pi / 4]$ based on above information, which one of the following statement is incorrect? (Speed of sound in air is $300 \,ms ^{-1}$ )
