Waves $y_{1} = 3 sin (2 x - 4 t)$ and $y_{2} = 3 sin (2 x + 4 t)$ (cm) form a standing wave. Which statements are correct?

Options:(select one or more)

Answer:

A, B, C

Solution:

$y = 6 sin 2 x cos 4 t$ . Nodes: $2 x = nπ$ . Antinodes: $2 x = π /2, 3 π /2$ . At $x = π /12$ : $6 sin (π /6) = 3$ cm. At $x = π /4$ the amplitude is 6 cm (D false).
