The equation of a wave is y = 6 sin [ 4 π ( 2 t − 2 1 x ) ] ( y , x in cm, t in s). Which statements are correct?

ω = π /2 , k = π /8 . λ = 16 cm, v = 4 cm/s, f = 0.25 Hz, travel along + x . ω Δ t = π /2 for 1 s. k ⋅ 4 = π /2 = 9 0 ∘ , not 4 5 ∘ .

The equation of a wave is $y = 6 sin [\frac{π}{4} (2 t - \frac{1}{2} x)]$ ( $y, x$ in cm, $t$ in s). Which statements are correct?

Options:(select one or more)

Answer:

A, C

Solution:

$ω = π /2$ , $k = π /8$ . $λ = 16$ cm, $v = 4$ cm/s, $f = 0.25$ Hz, travel along $+ x$ . $ω Δ t = π /2$ for 1 s. $k \cdot 4 = π /2 = 9 0^{\circ}$ , not $4 5^{\circ}$ .
