$Assertion :$ Doppler formula for sound wave is symmetric with respect to the speed of source and speed of observer.
$Reason :$ Motion of source with respect to stationary observer is not equivalent to the motion of an observer with respect to stationary source.

- 3A narrow tube is bent in the form of a circle of radius $R,$ as shown in the figure. Two small holes $S$ and $D$ are made in the tube at the positions right angle to each other. A source placed at $S$ generated a wave of intensity $I_0$ which is equally divided into two parts : One part travels along the longer path, while the other travels along the shorter path. Both the part waves meet at the point $D$ where a detector is placed If a maxima is formed at the detector then, the magnitude of wavelength $\lambda$ of the wave produced is given by $\pi R$View Solution
