Two waves of amplitudes $A_0$ and $x A_0$ pass through a region. If $x > j _0$ the difference in the maximum and minimum resultant amplitude possible is
A$(x+1) A_0$
B$(x-1) A_0$
C$2 x A_0$
D$2 A_0$

D$2 A_0$
d (d)
Amplitudes are $A_0$ and $x A_0$
$\therefore$ Maximum amplitude where they are/n phase are $A_0+x A_0$. Minimum amplitude $x A_0-A_0$
Difference between the two $=2 A _0$.

A tuning fork of frequency $340Hz$ is vibrated just above the tube of $120 cm$ height. Water is poured slowly in the tube. What is the minimum height of water necessary for the resonance .... $cm$ (speed of sound in the air $= 340 m/sec$)
A steel wire with mass per unit length $7.0 \times 10^{-3}\,kg\,m ^{-1}$ is under tension of $70\,N$. The speed of transverse waves in the wire will be $.........m/s$
An observer moves towards a stationary source of sound of frequency $n$. The apparent frequency heard by him is $2n$. If the velocity of sound in air is $332\, m/sec, $ then the velocity of the observer is .... $m/sec$
A wave is propagating along $x$-axis. The displacement of particles of the medium in $z$-direction at $t = 0$ is given by: $z =$ exp$[ -(x + 2)^2]$ , where $‘x’$ is in meters. At $t = 1s$, the same wave disturbance is given by: $z =$ exp $ [ - (2 - x)^2 ]$. Then, the wave propagation velocity is
A source and an observer move away from each other with a velocity of $10\; m/s$ with respect to ground. If the observer finds the frequency of sound coming from the source as $1950 \;Hz$, then actual frequency of the source is .... $Hz$ (velocity of sound in air = $340\; m/s$)
The particles of a medium vibrate about their mean positions whenever a wave travels through that medium. The phase difference between the vibrations of two such particles
A stationary wave is represented by $y=A \sin (100 t) \cos (0.01 x)$, where $y$ and $A$ are in millimetres, $t$ is in second and $x$ is in metre. The velocity of the constituent wave is ........... $m / s$
