The displacement of two sinusoidal waves is given by the equation $y_{1} = 8 sin (20 x - 30 t) y_{2} = 8 sin (25 x - 40 t)$ then the phase difference between the waves after time $t = 2 s$ and distance $x = 5 cm$ will be

Options:

Answer:

Solution:

$y_{1} = 8 sin (20 x - 3 t)$ Substituting $x = 5 cm$ and $t = 2 s$ , $y_{1} = 8 sin (40)$ Similarly, $y_{2} = 8 sin (45)$ $∴$ phase difference $= 45 - 40 = 5$ radian
