A uniform string suspended vertically. A transverse pulse is created at the top most of the string. Then
speed of pulse remains constant
the speed of the pulse decreases with constant rate as pulse moves downward.
the speed of the pulse decreases with increasing rate as pulse moves downward
the speed of the pulse increases with constant rate as pulse moves downward
Two monoatomic ideal gases $1$ and $2$ of molecular masses $M_1$ and $M_2$ respectively are enclosed in separate containers kept a the same temperature. The ratio of the speed of sound in gas $1$ to that in gas $2$ is
Fundamental frequency of a sonometer wire is $n$. If the length and diameter of the wire are doubled keeping the tension same, then the new fundamental frequency is
Figure shows a sinusoidal wave at a given instant Which points are in same phase ?
Two waves of sound having intensities $I$ and $4I$ interfere to produce interference pattern. The phase difference between the waves is $\pi /2$ at point $A$ and $\pi$ at point $B$. Then the difference between the resultant intensities at $A$ and $B$ is
A closed organ pipe has length $L$ , the air in it is vibrating in third overtone with maximum amplitude $'a'$ . The amplitude at distance $\frac {L}{7}$ from closed end of the pipe is
