Two plane progressive waves travelling on a string as aligned & y₁=2.5 10⁻³ (30 x-420 t) & y₂=2.5 10⁻³ (30 x+420 t) aligned superimpose to produce a standing wave. The variables x and y are in meter and t is in second. Then

Options

  1. Athe equation of resultant standing wave is y=5 10⁻³ (30 x) (420 t)
  2. Bthe equation of resultant standing wave is y=2.5 10⁻³ (30 x) (420 t)
  3. Cthe antinode closest to x=0.25 ~m is at x=0.262 ~m
  4. Dthe amplitude of oscillation of particle at x=0.17 ~m is 4.63 mm

Two wires made of the same material, one thick and the other thin, are connected to form a composite wire. The composite wire is subjected to some tension. A wave travelling along Two identical loudspeakers, placed close to each other inside a room, are supplied with the same sinusoidal voltage. One can imagine a pattern around the loudspeakers with areas ofThe frequency of the sound produced by a siren increases from 400 Hz to 1200 Hz while its amplitude remains the same.
