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
A string $1\,m$ long is drawn by a $300\,Hz$ vibrator attached to its end. The string vibrates in three segments. The speed of transverse waves in the string is equal to ..... $m/s$
A point source emits sound equally in all directions in a non-absorbing medium. Two points $P$ and $Q$ are at a distance of $9$ meters and $25$ meters respectively from the source. The ratio of the amplitudes of the waves at $P$ and $Q$ is
A train standing at the outer signal of a railway station blows a whistle of frequency $400\, Hz$ in still air. What is the frequency of the whistle for a platform observer when the train recedes from the platform with a speed of $10\, m/s$ ...... $Hz$ . (Speed of sound $= 340\, m/s$)
Figure shows a sinusoidal wave at a given instant Which points are in same phase ?
The two waves represented by $y_1 = a\,sin(\omega\,t)$ and $y_2 = b\, cos\, (\omega\, t)$ have a phase difference of
