MCQ
The phenomenon of beats can take place:
​​​​​​
  • A
    For longitudinal waves only.
  • B
    For transverse waves only.
  • For both longitudinal and transverse waves.
  • D
    For sound waves only.

Answer

Correct option: C.
For both longitudinal and transverse waves.
When two or more waves of slightly different frequencies $\left(v_1-v_2>10\right)$ travel with the same speed in the same direction, they superimpose to give beats.
Thus, the waves may be longitudinal or transverse.

A ring of mass $M$ and radius $R$ is rotating with angular speed $\omega$ about a fixed vertical axis passing through its centre $O$ with two point masses each of mass $\frac{ M }{8}$ at rest at $O$. These masses can move radially outwards along two massless rods fixed on the ring as shown in the figure. At some instant the angular speed of the system is $\frac{8}{9} \omega$ and one of the masses is at a distance of $\frac{3}{5} R$ from $O$. At this instant the distance of the other mass from $O$ is
