Y=5sin (3x -4t) Cdculate the wavelength frequency and period.

Pls answer and explanation with formula

The correct answer is c

i believe the answer is a

explanation

the general form of wave equation is

y=Asin(kx-wt)

we have

y=5sin(3x-4t)

hence the angular frequency

w= 4s^-1

the frequency

f=w/2 pi

f=4/2 pi

f=4/2*3.14

f=0.64 hz

the period

T=1/f

T=1/0.64

T=1.5625=1.6

the wavelength

k=2 pi/lambda

lambda=2 pi/k

k=3

so

lambda=2*3.14/3

lambda=2.09

if my answer is right then mark me brainlist
