A sound wave $y = a sin (ω t - k x)$ travels in a medium of bulk modulus $B$ . Which statements are correct?

Options:(select one or more)

Answer:

A, B, C

Solution:

$Δ P = B ak cos (ω t - k x)$ . Its amplitude is $B ak$ , which grows with $k$ (D false). It leads $y$ by $π /2$ and is maximum where $cos = 1$ , that is where $y = 0$ .
