Equation of a progressive wave is given by y = a sin π [ 2 t − 4 x ] , where t is in seconds and x is in meters. The distance through which the wave moves in 8 sec is (in meter):

ω = π /2 , k = π /4 , so v = ω / k = 2 m/s. In 8 s the wave moves 2 × 8 = 16 m.

Equation of a progressive wave is given by $y = a sin π [\frac{t}{2} - \frac{x}{4}]$ , where $t$ is in seconds and $x$ is in meters. The distance through which the wave moves in 8 sec is (in meter):

Options:

Answer:

Solution:

$ω = π /2$ , $k = π /4$ , so $v = ω / k = 2$ m/s. In 8 s the wave moves $2 \times 8 = 16$ m.
